| Abstract: | It is an important Technological method to attain TiB2-base ceramic-metal composites coatings on carbon steel by laser cladding.The thermodynamics and dynamics of TiB2 and Ni in the melt pool of laser cladding,and the interface between ceramic and metal have been studied on theory.Further more,some measures about how to improve the wettability and bonding strength of phase interface ceramic-metal have been brought out,which have provided a guide,for attainting high quality TiB2-base ceramic-metal composites coatings,and the design of process parameters. |
