摘要：

Laser cladding technology is an advanced surface modification technology. By selecting different parameters and coating materials, the surface hardness and wear resistance of titanium alloys can be effectively improved. The cladding material is a key factor affecting the quality and performance of the cladding layer. Common cladding materials mainly include self-fluxing alloy powder, ceramic powder and rare earth element powder. This paper reviews the current research status of laser cladding material system on titanium alloy, and explains the problems that still need to be solved and puts forward the outlook.
