| Abstract: |
| Electrochemical corrosion behaviors of Zn4Al3Mg-xIn solder alloys were studied in this work by potentiodynamic polarization measurements. And the high-temperature oxidation resistance of the solders was also investigated by thermogravimetric analysis (TGA). The results show that: the corrosion potential of Zn4Al3Mg solder is less than -1.15V, which means the corrosion tendency of Zn4Al3Mg-xIn alloys can not be neglected, and the corrosion potential decreased with the increase of In content. Obvious regional corrosion and pitting corrosion were observed on the surface of Zn4Al3Mg-xIn alloys by SEM.The TGA results indicate that slow progress of oxidation took place at 260 ℃, Zn4Al3Mg-xIn alloys show good oxidation resistance. |
