Abstract：
Electrochemical corrosion behaviors of Zn4Al3Mg-xIn solder alloys were studied 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 Zn4A13Mg solder is less than -1.15 V, which means the corrosion tendency of Zn4A13Mg-xIn alloys cannot be neglected. The corrosion potential decreases with the increase of In content. Obvious regional corrosion and pitting corrosion are observed on the surface of Zn4Al3Mg-xIn alloys by SEM. The TGA results indicate that slow progress of oxidation takes place at 260 degrees C, and Zn4Al3Mg-xIn alloys show good oxidation resistance.
