【摘要】:采用电化学极化法研究了Zn4Al3Mg-xIn合金钎料的腐蚀行为,采用热重分析(TGA)方法研究了该合金的高温氧化性能。结果表明:Zn4Al3Mg-xIn合金的腐蚀电位小于 1.15 V,腐蚀倾向大,且随着In含量增加,合金的腐蚀电位减小,腐蚀倾向增大。SEM结果表明,Zn4Al3Mg-xIn合金表面出现了严重的区域腐蚀和孔蚀。TGA结果表明,Zn4Al3Mg-xIn合金在260℃下,氧化进度缓慢,合金表现出较好的抗高温氧化性能。
[Abstract]:The corrosion behavior of Zn4Al3Mg-xIn alloy was studied by electrochemical polarization method. The high temperature oxidation behavior of Zn4Al3Mg-xIn alloy was studied by thermogravimetric analysis (TGA). The results show that the corrosion potential of wt Zn _ 4AL _ 3Mg-xIn alloy is lower than that of 1.15V, and the corrosion potential decreases with the increase of in content. The results of SEM show that the surface of Zn-4Al3Mg-xIn alloy has serious regional corrosion and pitting corrosion. TGA results show that the oxidation progress of ZZn-4Al3Mg-xIn alloy is slow at 260 鈩,
