Abstract:The functional composite coatings on Ti6Al4V alloy surface prepared by laser cladding can greatly improve the friction and wear behavior and high temperature oxidation resistance, which resu1ts in a widespread application in aeronautics and astronautics, energy resources, chemical industry and biomedical materials fields. In this paper, the research of functional composite coatings on the surface of Ti6Al4V alloy prepared by laser cladding is reviewed. In addition, a variety of performance characteristics, applications and development of the material systems about functional composite coatings are summarized. The deficiency and new design philosophy of functional composite coatings by laser cladding are also proposed.
