Abstract: In order to deeply understand the development status of laser remanufacture of titanium alloys, the research progress of laser remanufacturing of titanium alloy was reviewed from the aspects of remanufacturing materials, processes, and methods. The remanufacturing characteristics and applications of metal alloy powder, ceramic powder, rare earth and its oxide powder coatings were described. The effects of main process parameters on the morphology and properties of coatings were discussed. The applications of numerical simulation, auxiliary process and composite process in laser remanufacturing of titanium alloy parts were discussed. Finally, the development trend of laser remanufacturing of titanium alloy parts was prospected.
