摘要(Abstract)：

在20碳钢和Zn-6%Al-3%Mg合金液中分别添加0.6%Zr,用扫描电镜和X射线衍射仪研究了锆元素对20碳钢在Zn-6%Al-3%Mg锌合金液中腐蚀行为的影响。结果表明:20碳钢在510℃的Zn-6%Al-3%Mg和Zn-6%Al-3%Mg-0.6%Zr合金液中的腐蚀程度都随侵蚀时间的增加而增大,但是20碳钢在Zn-6%Al-3%Mg-0.6%Zr合金液中的腐蚀程度明显减轻。随着侵蚀温度的升高,20碳钢在Zn-6%Al-3%Mg-0.6%Zr合金液中的腐蚀深度由缓慢增加转为急剧增大,为减少Zn-6%Al-3%Mg-0.6%Zr合金液对碳钢的腐蚀程度,热浸镀锌温度应低于510℃。含0.6%Zr的20碳钢在Zn-6%Al-3%Mg合金液中经过长时间侵蚀后,可形成较厚的致密Fe-Al化合物层,使含锆20碳钢的腐蚀速率明显低于20碳钢,因此在钢中添加0.6%的锆元素可提高钢制锌锅的使用寿命。
