    摘要:

    本文采用電化學(xué)極化法研究了Zn4Al3Mg-xIn合金釬料的腐蝕行為，采用熱重分析（TGA）方法研究了該合金的高溫氧化性能。結(jié)果表明：Zn4Al3Mg-xIn合金的腐蝕電位小于-1.15V，腐蝕傾向大，且隨著In含量增加，合金的腐蝕電位減小，腐蝕傾向增大。SEM結(jié)果表明，Zn4Al3Mg-xIn合金表面出現(xiàn)了嚴(yán)重的區(qū)域腐蝕和孔蝕。TGA結(jié)果表明，Zn4Al3Mg-xIn合金在260℃下，氧化進(jìn)度緩慢，合金表現(xiàn)出較好的抗高溫氧化性能。

    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.
