metallurgy cell
1.The microstructure of bioceramic coating on TC4 by laser cladding was studied by XRD,SEM etc The results show that the coating layer is composed of HA etc Ca P based phases There are some precipitation of finer granular in the directional cell grains and second phase in the interface between grain There is a chemical metallurgy bonding between the coating layer and metal substrate It is increased to be similar to the microstructure of body bone
