Abstract In current investigation micro arc oxidation of Ti6Al7Nb alloy was done to improve its surface properties and corrosion resistance. Mixture of Na2SiO3, Na3PO412H2O and KOH is used as electrolyte. MAO treated Ti6Al7Nb specimens were examined using x-ray diffraction (XRD), energy dispersive spectroscopy (EDS) and scanning electron microscopy (SEM) to examine their morphology and phase composition. It was observed that electrolyte composition is simultaneously included in the growing oxide layer during MAO process. From electrochemical study it was found that corrosion resistance of the Ti6Al7Nb increases during EIS testing in 0.9% NaCl solution. It was found that frequency, duty cycle, current and processing time effect the surface roughness, thickness, hardness and corrosion resistance of coating. Out of above mention parameters frequency and duty cycle has major impact on performance parameters. The objective of current investigation is to find out effects MAO process parameters on coating performance parameters such as coating thickness, hardness, surface roughness and corrosion resistance. At duty cycle of 50%, frequency 500 Hz, current 300 mA and processing duration 7.5 min, highest coating thickness 32.96 μm and surface roughness 3.3680 μm was obtained. Process parameters have the influence on pore size, biggest average pore size 3.8519 μm was obtained at duty cycle of 50%, frequency 500 Hz, current 300 mA and processing duration 7.5 min. Grey relational analysis is done to determine which process variable has the most influence on performance parameters. From grey relational analysis technique, it was observed that duty cycle 50%, frequency 500 Hz, current 300 mA, and processing time 7.5 min are ideal process parameters for higher coating thickness, hardness, surface roughness and better corrosion resistance. From grey relation analysis it was also found that frequency has most significant impact on performance parameters after that duty cycle, then current and at last processing time.

Biomaterials come in numerous types, including composite, metallic, ceramic, and polymeric materials. For the creation of different implants, screws, and plates, metallic biomaterials are utilised. Crucial metallic biomaterials include zinc, titanium, magnesium, Cr–Co alloys, stainless steel, and magnesium metal. Most of the abovementioned biomaterials have excellent properties; nevertheless, for long-term therapeutic use, they are unsuitable as they are bio-inert and unable to form a direct link with living bone soon after being inserted into a human being. There is a need for a biocompatible coating on these implants because most of the metallic biomaterials discussed above lack biocompatible properties. These materials must have their surfaces modified to fulfil clinical requirements since they play a significant role in responding to artificial devices in a biological context. Using the right surface modification techniques, biomaterials may be selectively enhanced while maintaining their desirable bulk qualities, such as biological properties and corrosion resistance. Their application in the biological sector is expanded by the appropriate surface treatment. Designing biomaterials for implants requires careful consideration of biocompatibility properties. The surface chemistry, porosity, roughness, feature, and crystallinity are the main surface quality factors that influence biocompatibility. It was observed that the biocompatible coating can increase the biocompatibility of biomaterials. Numerous methods, including sol–gel, magnetic sputtering, physical vapor deposition, chemical vapor deposition, and micro-arc oxidation, can enhance the biocompatibility of metallic implants. Through the observation of cell behaviors such as differentiation, proliferation, and viability, biocompatibility may be evaluated in vitro. In the context of biomedical engineering, this book chapter examines various surface modification approaches for biocompatible coatings, such as mechanical, chemical and electrochemical treatments, thermal spraying, sol–gel, and ion implantation. Based on data from the literature, this book chapter critically examines how surface quality affects the biocompatibility of biomaterials. This study illustrates the beneficial effects of different surface modification approaches, as recommended by several research groups.

Abstract One of the most significant alloys to be employed in the automotive, aerospace, and military industries in recent years is A356 aluminium. Because of A356’s excellent compatibility with other metals and nanoparticles, novel hybrid composites may be made using it. The characteristics of these hybrid composites are mostly the result of the additives’ interaction with the A356 alloy’s current elemental composition. Aluminium composites were synthesized through stir casting method by reinforcing 2%, and 4% SiC, 2% and 4% Al2O3 and 0.5%, 1%, 1.5%, 2% and 2.5% SiC and Al2O3 both. The homogeneous distribution of SiC and Al2O3 microparticles in reinforced composite is revealed by scanning electron microscopy (SEM). The addition of SiC and Al2O3 reinforcements greatly improved the mechanical characteristics of the synthesised composites; for example, a composite with 4% SiC reinforcement reached its maximum hardness and maximum tensile strength of 165 HV and 257 MPa respectively. Maximum elongation of 6.72% was observed for 0.5% SiC and 0.5% Al2O3 reinforced composite. Minimum wear rate is observed for 4% SiC reinforced composite material. This study aims to identify gaps in the potential variations and compatibility of various additives with one another in order to create a brand-new hybrid reinforced alloy suitable for automotive braking system applications: brake rotors made of a disc or a brake pad, depending on the properties of the hybrid reinforced alloy that was made. Hence, the current work presented focuses on the preparation of hybrid reinforcement of A356 with silicon carbide and alumina powders.

<div>This research looks into how abrasive water jet machining (AWJM) can be used on carbon fiber-reinforced polymer (CFRP) materials, specifically how the kerf characteristics change with respect to change in process parameters. We carefully looked into four important process parameters: stand-off distance (SOD), water pressure (WP), traverse rate (TR), and abrasive mass flow rate (AMFR). The results showed that as SOD goes up, the kerf taper angle goes up because of jet dispersion, but as WP goes up, the angle goes down because jet kinetic energy goes up. The TR was directly related to the kerf taper angle, but it made the process less stable. The kerf drop angle was not greatly changed by AMFR. When it came to kerf top width, SOD made it wider, WP made it narrower, TR made it narrower, and AMFR made it a little wider. When the settings (SOD: 1 mm, WP: 210 MPa, TR: 150 mm/min, AMFR: 200 g/min) were optimized, the kerf taper angle and kerf top width were lowered. This improved the accuracy of the measurements and cut down on material waste in CFRP composite machining. These results make it clear how important parameter selection is in precision cutting.</div>

The development of lightweight and high-strength materials is critical for many industries, including aerospace, automotive, and electronics. Metal matrix composites (MMCs) have shown great promise in meeting these requirements. The structural and physical properties of Al6061 alloy reinforced with hybrid MMCs, including TiB2, SiC, and fly ash (FA), were investigated in this research review. The MMCs investigated were made using the stir-casting process. Their microstructure, structural characteristics, and mechanical features were examined. The inclusion of TiB2 and SiC enhanced the composite’s hardness, tensile strength, and wear resistance, while the addition of FA lowered its density and improved its thermal and corrosion resistance. However, the volume percentage, particle dimension, and arrangement of the reinforcing components all had an effect on the physical characteristics of the composite. Therefore, the optimum combination of the reinforcing materials must be carefully selected to achieve the desired properties. The result of this review provides valuable insights into the development of high-performance MMCs for various industrial applications.

As implant materials, titanium and its alloys have been extensively utilized because of their exceptional mechanical properties and biocompatibility. Despite this, corporations and researchers alike have kept up their aggressive pursuit of better alloys since there are still issues that require immediate attention. One of these causes a problem with stress shielding as a noticeable variation in the elastic modulus of the implant material. Ti alloys release harmful ions after extended usage. The poor bioactivity of the Ti alloy surface slows the healing process. In order to address these problems, additional research has concentrated on developing Ti alloys for the 21st century that contain a more suitable phase and change the surface of the alloy from inherently bioinert to bioactive. This study assesses the knowledge presently existing on the biological, chemical, mechanical, and electrochemical characteristics of important [Formula: see text]-Ti alloys created in recent years with the objective to provide scientific justification for using [Formula: see text]-titanium-based alloys as a substitute for cpTi. Dental implants might be made using [Formula: see text]-Ti alloys as an alternative. The enhanced alloy qualities, which include a lower modulus of elasticity, improved strength, suitable biocompatibility, and good abrasion and excellent resistance to corrosion, offer the essential proof. Additionally, structural, chemical, and thermomechanical modifications to [Formula: see text]-Ti alloys allow for the production of materials that may be tailored to the needs of unique instances for clinical practises. By researching the paper, the performance and attributes of [Formula: see text]-titanium alloy are compared to those of other forms of titanium alloy, such as [Formula: see text] titanium alloys. To support their usage as cpTi substitutes, in vivo studies are required to assess new [Formula: see text]-titanium alloys.

AbstractTitanium and its alloys have already been widely used as implant materials due to their outstanding mechanical characteristics and biocompatibility. Notwithstanding this, researchers and businesses alike have continued to actively pursue superior alloys since there are still problems which need urgent consideration. One of these is a noteworthy difference in the implant material’s elastics modulus and that of natural bone, which result into an issue of stress shielding. With prolonged use Ti alloys releases dangerous ions. The Ti alloy surface has a low bioactivity, which prolongs the healing process. β-Ti alloys could be used as viable alternatives when creating dental implants. Additionally, β-Ti alloys characteristics, such as low Young modulus, increased strength, appropriate biocompatibility, and strong abrasion and corrosion resistance, serve as the necessary evidence. Ti alloys when altered structurally, chemically, and by thermomechanical treatment thereby enabling the creation of material which can match the requirements of a various clinical practise scenarios. Additional research is needed which can focused on identifying next century Ti alloys consisting of some more compatible phase and transforming the Ti alloys surface from intrinsically bioinert to bioactive to prevent different issues. In order to give scientific support for adopting β-Ti-based alloys as an alternative to cpTi, this paper evaluates the information currently available on the chemical, mechanical, biological, and electrochemical properties of key β-titanium alloys designed from the past few years. This article is also focusing on β-titanium alloy, its properties and performance over other type of titanium alloy such as α titanium alloys. However, in-vivo research is needed to evaluate novel β titanium alloys to support their use as cpTi alternatives.

Over the past few years, 3D-printed biomaterials have gained widespread usage in the manufacturing of orthopaedic implants. 3D-printed implants have low weight, minimal material waste, ease of creation, the capacity to create complex topological implants that are patient specific, and a porous structure that permits tissue development. 3D printing has the potential to reduce material waste, cut transportation costs, optimise manufacturing costs, streamline the supply chain in supply chain management (SCM), and enhance environmental sustainability by utilising the concept of production-on-demand (POD). Biopolymer-based composites consisting of cellulose, chitin, and chitosan are sustainable materials that may be utilised as necessary. In light of the present biomedical issues, hydroxyapatite and starch combinations have immense potential for generating sustainable biomaterials. Carbon, which is a key category of sustainable biomaterials, is found in a wide range of carbonaceous gels and biomaterials based on cellulose fibres and carbon nanotube. The goal of this article is to give a thorough review of a few of the most recent developments, uses, and challenges for biomaterials made from sustainable resources. In this article, the authors have initially covered different biomaterials such as metallic, polymeric, ceramic, and composite and their properties and applications. Sustainable manufacturing techniques for biomaterials such as 3D and 4D printing are also covered in this article. Different sustainable biomaterials are covered with their properties and applications such as protein-based, cellulose, chitin, and chitosan composite-based, hydroxyapatite-starch-based and carbonaceous biomaterials. At last, future scope and opportunities in sustainable biomaterials and manufacturing techniques are covered. It has been found out that 3D printing technologies may support circular production systems across a range of sectors including biomedical by permitting the use of recycled and recovered materials as raw materials only when necessary.

Magnesium alloys are suitable biological material because of its favourable mechanical qualities, high biocompatibility, and biodegradability. However, it has poor corrosion resistance and has rapid dissolution in the corrosive environment which will weakens its mechanical characteristics. The surface characteristics of magnesium alloy must thus be changed using a suitable surface modification technology, such as micro arc oxidation (MAO). This article examines recent developments and advancements in biodegradable surface coatings applied to magnesium alloys. It was observed there are four steps of MAO process, the formation of a thinner and denser barrier, commencement of oxides in bare Ca-Mg matrix following the presence of sparks; the horizontal expansion of the oxide layer, and finally thickening of MAO coating. It was observed that characteristics of MAO coating can changed by varying electrical parameters like duty cycle, current density, type of power output, frequency, and processing time. It was noticed that when all other factors are held constant, duty cycle, processing time, and frequency primarily effect the coating's porosity, number of cracks and thickness, which in turn influences how well the coating performs. DC, AC, pulsed bipolar, and pulsed unipolar, are the four categories into which the current regimes are classified. It was found that, unipolar current mode MAO coatings found to be rough, highly porous, and vulnerable to microcracks due to stronger spark discharge. MAO coating produced in a bipolar current type of mode have larger pores but are more uniform in thickness and compact. It was noticed that the in-vitro cell assays showed cells L929 on the Ca-P coated Mg alloy to have considerably good adhesion, a high growth rate, and strong proliferation (p 0.05). In other words, the cytocompatibility was greatly enhanced by the Ca-P coating. It was discovered that the Ca-P coated Mg alloy improved cell responsiveness and encouraged early bone formation at the implant/bone interface by both conventional pathological examination and immunohistochemistry investigation. The Ca-P coating was found to be an effective method for raising the surface bioactivity of Mg alloy. It was also observed that the calcium phosphate coating deposited by MAO process improve surface biomineralization which is the main mechanism behind bioactivity. Functional groups that are present on surface engage electrostatically through calcium and phosphate ions from solutions to start the biomineralization process. Calcium phosphates have excellent biocompatibility and are quite comparable to the mineral makeup of bone. The current study aims to investigate the bioactivity of calcium phosphate coatings and the characteristics of magnesium and its alloys.
