| Abstract: | The metalioscope, SEM and globe are used here to study the joint mode, microstructure. and diffusion of aloying elements of the interface of the bimetall hammer inlayed a piece of high-Cr iron. It is deemed that the parent materials and inlays joint in two ways: metallurgical bonding and mechanical contacts. They exist together in the same interface. There is no gap between the metallurgical bonding interface and alloying element diffuse largely. The joint strenth of the interface is therefore high. The paper also discusses the defects such as shinkage cavities. inclusions and cracks. Ways to prevents them are given. |
