Progress in Laser Surface Modification Technology of Titanium Alloy

Abstract Titanium alloys have limited application in friction and wear environments due to their low surface hardness and poor wear resistance. By preparing a coating that improves wear resistance and high temperature oxidation resistance on the surface of the titanium alloy, the wear and corrosion resistance of the titanium alloy can be significantly enhanced, thereby greatly broadening its application fields and reducing production costs. Starting from the process, this paper systematically explained the current research status of surface laser modification technology at home and abroad, discussed the existing problems and corresponding solutions, and predicted the future development trend of the technology.
