چکیده انگلیسی
Corrosion mechanism of Zn-30Sn high-temperature, lead-free solder in neutral 0.5â¯M NaCl solution are investigated by using FE-SEM, XRD, XPS and SIMS. The results confirm that α-Zn phases are corroded preferentially. Moreover, during initial corrosion process, a double-layer structure of ZnO and Zn(OH)2 is formed, providing beneficial barrier effect hindering the penetration of Clâ. However, subsequent morphology transformation weakens barrier effect to Clâ penetration and results in severe corrosion. Mechanism of surface layer breakdown and internal corrosion propagation are further examined, where it is determined that aggressive Clâ plays an important role in the corrosion process of Zn-30Sn solder.
