Effects of P Addition on the Oxidation and Corrosion Behavior of Sn-9Zn-1Bi Solder Alloy

Article Preview

Abstract:

The oxidation and corrosion behavior of Sn-9Zn-1Bi lead-free solder alloys with different P content were investigated by weighing the mass of the alloy, as well as the effects of P on the microstructure. The results indicate that the oxidation resistance and the corrosion resistance of Sn-9Zn-1Bi solder alloy can be enhanced significantly with the increase of P content. The microstructure observations show that P addition into Sn-9Zn-1Bi solder alloy can refine the microstructure and the numbers of dark rod-like Zn-rich phases are decreased with increasing of P addition.
