Abstract

The Sn, Ni, P were added into AgCuZnSn brazing alloy. And the effects of Sn, Ni and P on the microstructure and property of AgCuZn cadmium-free brazing alloy system were investigated. The results showed that the wettability of the brazing alloy was improved with the addition of Sn. The addition of P could decrease the interfacial tension between liquid brazing alloy and specimen, and the wettability and fluidity were also improved. The microstructure of AgCuZn brazing alloy was consisted of Cu-rich phase, CuZn intermetallic compound, Cu_5.6Sn intermetallic compound, Cu_40.5Sn₁₁ intermetallic compound and Ag-rich phase. Dendrite that formed in the alloy microstructure make brazing alloy friable after the addition of Sn. The black Ni₃P compound was generated when Ni was added, and make microstructure homogeneous. The gray Cu₃P compound was generated when P was added.
