This paper proposes a method to sintering tungsten-copper alloy coating layer to copper plate surface.Sintering in the hydrogen after pre-compacted tungsten-copper alloy powder to the surface of the copper plate,compacted the pre-compacted powder by explosive sintering.Diffusion sintering at last in order to improve the coating layer density.The coating layer was up to 99.3%of the theoretical density.Microstructure characteristics indicated that tungsten copper powder well mixed.The size of the tungsten particles is larger than copper particles.The SEM fracture surface analysis is different from traditional fracture.Tungsten copper joint surface,analyzed by SEM,indicated that tungsten copper alloy sintered on the surface of the copper.
