| Abstract Scope |
This study investigated the microstructure of Zn-coated Al particle joints, the reaction layer at the interface between Zn-coated Al particles and Ni plates, and the shear strength. Zn-coated Al particles were prepared by subjecting Al particles to zincate treatment. Differential scanning calorimetry analysis revealed the presence of an endothermic peak at about 383℃, indicating the occurrence of eutectic melting at the interface between the Zn film and Al particle. Cross-sectional observation of the Ni joints prepared at a joining temperature of 400℃, joining pressure of 8 MPa, and joining time of 10-30 min revealed Ni-Al compound at the joining interface between the Zn-coated Al particles and the Ni plate. Shear tests showed that the shear strength of Ni joints increased with increasing joining time. |
