By laser cladding magnesium-cobalt alloy on the surface of titanium alloy, the problems of wear on the surface of titanium alloy material and insufficient damping performance of the material in the aerospace field are solved. The laser power and magnesium-cobalt mixture ratio were compared and the experimental results were analyzed. The experimental results show that when the laser power is 235.2 w and the mixing ratio of magnesium and cobalt is 1∶300, the cladding effect is the best. The experimental samples under these conditions were characterized by scanning electron microscopy and eds elemental spectrum analysis. the results showed that ti elements in the matrix and co and mg elements in the cladding layer infiltrated each other after laser cladding, and the elements were evenly distributed in the matrix and cladding layer. The further test results show that the co and mg concentrations in the cladding layer have been increased to a certain extent by completely cladding the cladding material onto the surface of the substrate.
