【Abstract】 The effect of the processing of different methods of surface treatment on the shear strength of interface of Cu/Mo/Cu composite was investigated. The microstructure of Mo/Cu interface was observed by using optical microscope (OM) and scanning electron microscope (SEM). The processing methods of the surfaces treatment have an important effect on the cladding sheets. The shear strength of the Cu/Mo interface of the cladding sheet treated with sandblasting plus chemical method has the highest values, and the cladding sheet treated only with normal chemical method had the lowest shear strength. The bonding mechanisms of the interface of Cu/Mo/Cu cladding sheets treated with sandblasting plus chemical method are composed of the fracture of surface membrane and hardened surface, energy activation and mechanic joggle of the mating surfaces.更多还原
