The emergence of carbon nanotubes (CNT) has encouraged widespread interest among researchers with many pioneering applications achieved by exploiting the unique properties of carbon allotropes. This article is a general overview of the diversity of applications of CNT and their various forms, particularly, in the area of surface coatings. The different methods, which have been developed and practiced in the preparation, dispersion, functionalization, and metallization of CNT, are elucidated. The composite coatings have been prepared using electrochemical methods such as electroplating and electroless plating. The review presents the mechanical, electrochemical, corrosion, thermal, electrical conduction, tribological, biosensing, magnetic, and microwave absorbing properties of CNT-based composites. The incorporation of CNT substantially affects the coating performance, and the level of influence can be befittingly adjusted to suit the application needs. Various characterization studies have been conducted on these coatings, emphasizing their properties. The potential of CNT as a versatile material in catering to diverse industrial applications has placed the carbon allotrope among the elite group of materials, drawing the attention of researchers to widen their scope of utilization. The challenges, problems, and ways of the overcoming are also addressed in this review.

The advancement in fibre-reinforced polymer (FRP) innovation have a distinct fascination in executing another sort of strands named as basalt fibre reinforced polymer (BFRP), which has the dominating of being erosion safe, strong and cost effective that deliver a predominant outcome when applied in concrete structure. Besides, the accessible codal provision and aides does not give any suggestions to the use of Basalt bars since basic investigations and significant applications are as yet restricted. The objective of our investigation was progressed by two phases. The initial phase was led by examining the properties on BFRP and STEEL bars & these properties were evaluated and compared with the codal provision. The next phase of this test included testing of eight concrete beams (4 no’s of RC beam and 4 no’s of BFRP beam) of size 1700 mm long × 150 mm wide × 250 mm profound and to examine the flexural behaviour of both BFRP and RC beam under a two -point load over a clear span of 1550 mm until failure. The outcomes of these two phases were discussed in terms of its behaviour in crack, load, flexure and the mode of failure. Additionally, the test outcomes prove that the basalt bars have a great mechanical behaviour over concrete structures and it can be set as a substitution of STEEL bars for light, temporary structures.The advancement in fibre-reinforced polymer (FRP) innovation have a distinct fascination in executing another sort of strands named as basalt fibre reinforced polymer (BFRP), which has the dominating of being erosion safe, strong and cost effective that deliver a predominant outcome when applied in concrete structure.

The headway in fiber-fortified polymer (FRP) development have an unmistakable interest in executing another kind of strands named as basalt fiber strengthened polymer (BFRP), which has the overwhelming furthest reaches of being disintegration sheltered, solid and financially savvy that convey a prevalent result when connected in solid structure. Also, the available codal arrangement and associates does not give any proposals to the utilization of BFRP bars since fundamental examinations and noteworthy applications are up ’til now limited. The target of our examination was advanced by two stages. The underlying stage was driven by inspecting the properties on BFRP and STEEL bars& these properties were assessed and contrasted and the codal arrangement. The second period of this test included testing of eight solid bars (4no’s of RC bar and 4no’s of BFRP bar) of size 1700 mm long × 150 mm wide × 250 mm significant and to inspect the shear conduct of both BFRP and RC pillar under two - point stacking over a reasonable range of 1550 mm until disappointment. The results of these two stages were talked about as far as its conduct in split, load, shear and the method of disappointment. Moreover, the test results demonstrate that the basalt bars have an extraordinary mechanical conduct over solid structures and it very well may be set as a substitution of STEEL bars for light, transitory structuresThe headway in fiber-fortified polymer (FRP) development have an unmistakable interest in executing another kind of strands named as basalt fiber strengthened polymer (BFRP), which has the overwhelming furthest reaches of being disintegration sheltered, solid and financially savvy that convey a prevalent result when connected in solid structure.

Nickel-based multiwalled carbon nanotube (Ni–MWCNT) composite coatings were electrodeposited over the inner groove of an aluminim alloy rotor with Zn–Ni interlayer. The surface of the composite coating was investigated by X-ray diffraction and scanning electron microscopy. The hardness of the coating was determined by Vicker's method. It was revealed that Ni–MWCNT composite coating has uniformity in thickness over the surface of the aluminim groove and also better particle distribution over the area. It was found that there was a significant improvement in the microhardness values of Ni–MWCNT composite coating than uncoated aluminum alloy rotor. In addition, the wear resistance of the composite coated increased nine times than the uncoated substrate. Thus, Ni–MWCNT composite coated aluminum alloy rotor can enhance the performance and life-time of the rotor in the textile industries.

NiP–multiwall carbon nanotube composite coatings were deposited on a textile component at ∼14 µm thickness through electroless plating route. The composites were prepared by depositing four different concentrations of multiwall carbon nanotube (i.e. 100, 200, 300 and 400 mg L–1) in an electroless bath over four NiP substrates. The NiP–multiwall carbon nanotube composite coating was observed to have a remarkably lower surface roughness and higher micro-hardness – by about 50% in both cases – in comparison with the NiP electroless plated substrate without the incorporation of multiwall carbon nanotube. In addition to that, there was a 14% reduction in yarn to metal friction between the investigated cases. This particular enhancement was adduced to the addition of surfactant to the electrolytic bath. The superior homogeneity in the distribution of multiwall carbon nanotube in the nickel matrix and the formation of the Ni–C bond were also identified to drive the multiwall carbon nanotube towards much improved properties.
