Laser cladding experiment of Ti+TiC was carried out on Ti-6Al-4V alloy surface.The microstructure of the clad layer was observed by SEM.The microstructure and its formation mechanism have been explained by using a microstructure formation process model.The titanium based composite made from Ti+TiC powders by laser cladding has been analyzed from the aspects of preparation process,quality,technology,production cost and reinforcing effect.
