文摘

The preparation of composite solders by rapid solidification method is feasible. Al2O3 nano-particles can inhibit the growth of dendritic Sn-Zn eutectic. Al2O3 nano-particles can reduce the thickness of Al8ZnSn4 interface layer. Adding 1 wt% Al2O3 nanoparticles can improve wetting area and strength of soldered joint by 96.9% and 47.7%, respectively.
