盐雾测试的要求?
图纸要求:
1. ZINC PLATE PER ASTM B633 FeZn 8 TYPE III
(with * 96hour minimum salt spray to white corrosion).
*salt spray test is based on test panels
actual results will vary based on the plating process
2. color: clear, iridescent clear, or bright
查资料:
1. ASTM B633-07
疑问
1. TYPE III说明的要求最少盐雾测试时间为12h, 为何图纸上要求96h? 两者怎么理解?
2. *salt spray test is based on test panels
actual results will vary based on the plating process, 这两句话怎么理解, 实际过程中会有哪些现象发生才会用到?
3. 颜色要求是怎么回事, 不固定吗?

镀锌有蓝白、黑、五彩好几种
人家讲的是至少12小时,所有的要求应该是根据实际使用效果来制定的
盐雾时间的长短是与电镀后所上的封闭剂有关
