| Abstract: | Laser cladding WC reinforced Ni3Al intermetallic matrix composite coating is prepared by coaxial powder delivery. The optimum process parameters are tested. The compositions, microstructure and microhardness of laser cladding coating are analyzed and measured. The results show laser cladding coating without cracks and pores can be obtained. The excellent metallurgical bonding can be realized. WC particle additives should considerably improve the microhardness of the coating. |
