摘要：
Steel-bonded cemented carbide sheet considered as cladding was successfully bonded with carbon steel plate by a technological combination of powder explosive compaction and liquid sintering. The microstructural interface between steel-bonded cemented carbide cladding and carbon steel plate was characterized by SEM, EDS analysis and hardness testing. The results showed that the gradient distributions of the elements Fe, C and W were found in the normal direction of the interface. The element W permeated about 100 mu m in depth through the side of carbon steel. The improved hardness of about 600 similar to 700HV of cladding was attributed to multiple carbides.
