    ABSTRACT In this work, titanium aluminide alloy have been fabricated via the laser deposition technique. The effect of some selected deposition parameters on the microstructure and mechanical properties of produced deposits were studied. The relationship between the laser power, and the microhardness of deposited samples on laser preheated substrate showed an incremental change in laser power from 200 to 600 W. This led to an overall decrease in microhardness of deposited samples from 426 to 373 HV. Sample deposited at 500 W gave the lowest Icorr of 1.8 x 10-8 and the highest Ecorr of -0.138 V. It is evident from the nanoindentation results that indentation modulus and stiffness of sample deposited at 600 W laser power had a lower value compared with 400 W laser power. However, the modulus of both samples fell within titanium alloy modulus range between 105-120 GPa. The microstructures of the deposits are mainly characterized with γ-TiAl and α2-Ti3Al phases and an improved hardness property almost two times higher than that of commercially pure titanium were achieved. It was concluded that changes in the laser power directly causes changes in the microstructure, hardness, stiffness, modulus of elasticity and corrosion resistance of the deposits.

    Additive manufacturing (AM) is an important manufacturing technology that has changed the way products are designed and manufactured. Laser Metal Deposition (LMD), an AM technology, has the capability of producing components using a 3-Dimensional CAD model, through a layer by layer formation process just like any other AM technology. In this study, the influence of the scanning speed on the corrosion property of Titanium alloy-Ti6Al4V using LMD process was investigated. The scanning speed varied between 0.02 m/s and 0.14 m/s while other processing parameters were kept constant. The electrochemical corrosion test was conducted in sodium chloride (NaCl) solution. The result revealed that the corrosion resistance property was found to increase with the scanning speed.

    The unique properties of titanium and its alloys make them a continuous area of interest for the material researchers and high profile material industries. Titanium and its alloys possess high strength-to-weight ratio and excellent corrosion resistance properties which made them very useful for high temperature applications especially in areas such as energy generation, automobile and aeronautic industries. In this paper, the effect of deposition parameters on the properties of laser fabricated titanium aluminide alloy was studied. Titanium aluminide powder (Ti-4822-4) was deposited on pure titanium substrate using laser engineered net shaping (LENS) technique of additive manufacturing. Processing parameters like the laser power, scanning speed and powder flow rate were varied. Laser power was varied between 300 to 500 W, scanning speed varied between 3.174 to 7.406 mm s−1 and powder flow rate varied between 4.09 to 7.12 g min−1. The design and analysis of the results was carried out using design expert 6.0.8 software. The trends in deposits cracks, heights and microhardness in relation to the deposition parameters have been studied. The outcome of the study showed that cracks in the deposits reduced as the laser power increases and scanning speed reduces. It was also revealed that the overall microhardness increases as the laser power, scanning speed and powder flow rate increases. The height of the deposits increases as the laser power increases, scanning speed decreases and powder flow rate increases. Microscopic images of the deposits revealed massive presence of γ-TiAl and isolated lamellar region of γ-TiAl and Ti3Al.
