Abstract

Ti–6Al–4V alloy is a versatile material widely used in aerospace, chemical, and marine industries owing to its properties like lightweight, high strength, and corrosion resistant. However, the alloy lacks inadequate hardness and wear resistance to ensure a long product life for its applications. In this study, the Ti–6Al–4V alloy was coated with a metal matrix composite coating that consists of NiTi and TiN by TIG cladding process, and the wear behavior of the coated specimen was studied by conducting a pin-on-disk type tribological wear test. The effect of the sliding speed (by altering the rotational the speed of the disk) and the normal load applied on the wear or height loss of the pin-shaped-coated sample, and the coefficient of friction were studied. It was found that within the experimental domain, the produced NiTi–TiN coating is suitable for application in high load—lower speed and medium load—high-speed combinations.
