摘要：
The effects of corrosion on the shear strength of Cu/Sn-9Zn/Cu lap joints in 3.5 wt. % NaCl solution were investigated. The ultimate shear strength and yield strength of the lap joints decreased by 45% and 36% after immersion, respectively. The ductility of the lap joints also greatly decreased. X-ray diffraction and scanning electron microscopy characterizations of the corroded Cu/Sn-9Zn/Cu lap joints revealed the presence of corrosion byproducts. X-ray diffraction analysis confirmed that these byproducts were ZnO and ZnCl2. Pits and corrosion byproducts also formed on the surface of the corroded lap joints.
