摘要(Abstract)：

利用Wilhelmy吊板法测试原理,自制了表面张力测定仪,测定了Zn、Zn-Al、Zn-Al-Re锌浴在430～520℃下的表面张力,研究了温度、铝元素和稀土元素对锌浴表面张力的影响。结果表明:在430～520℃的范围内,纯锌浴的表面张力为0.744～0.782N·m~(-1),随着温度的升高而降低。与真空环境下纯锌浴表面张力相比,本实验测得值略小。在430～520℃范围内,向纯锌浴中添加了质量分数为0.05%～0.5%的铝,与纯锌浴的表面张力相比下降了1.66%～36.07%。在相同温度下,随着铝含量的增加,锌浴的表面张力降低。在430～520℃的范围内,在含0.2%铝的锌浴基础上添加了质量分数为0.2%和0.3%的稀土(Re),表面张力进一步降低了12.81%～16.11%。在相同温度下,随着稀土含量的增加,锌合金浴表面张力降低。在锌浴中添加相同质量分数元素的情况及相同温度下,相比于稀土,铝更能降低锌浴的表面张力。

关键词(KeyWords)： 锌铝合金;热浸镀;锌浴;表面张力
