In this study, composite coating with different rare earth oxides has been performed to enhance the surface, mechanical and tribological properties of titanium alloy using the TIG cladding process. Three different rare earth oxides, CeO 2 , La 2 O 3 and Y 2 O 3 were used in pairwise combination with WC and Ni powder. The cladding thickness, microstructure, phase analysis, microhardness and friction wear of coated samples were examined. The experimental results showed that mainly hard phases like NiTi and AlTi 2 C were found in coatings. The sample prepared with RE oxides refines the coating grains and enhances the mechanical and tribological properties. The wear test analysis reveals a considerable decrease in coefficient of friction (COF). The mechanism for the wear of coating was adhesion. The coating done with CeO 2 and La 2 O 3 has the highest microhardness (870 HV 0.5 ) and wear resistance (COF of 0.22), which confirmed that this combination of RE oxide is appropriate for surface modification.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
