Research Progress of Laser Cladding on Surface of Titanium Alloy

Abstract

Titanium alloy with the advantages of low density,high specific strength,good corrosion resistance is widely used in aerospace and other fields.However the characteristics of titanium alloy with low wear resistance and poor high-pemperature oxidation resistance limit its application.Improving the surface properties of titanium alloy by laser cladding technology has become a hot spot in the area of surface modification on titanium alloys.Present advancement in laser cladding materials on the surface of titanium alloy is introduced and summarized.Application of laser cladding technology is analyzed.And the development trend of the future is also proposed.
