良好的抗腐蚀性能（Good corrosion resistance）

对45钢在不同工艺处理的样品按ASTMBI17标准进行了连续喷雾试验,结果表明:经过QPQ处理的样品抗腐蚀性是发黑处理的16倍,是镀锌处理的6倍以上,是镀铬处理的3倍以上,是镀镍铬处理的2倍。

Continuous spraying tests were carried out on 45 steel in different processing samples according to ASTMBI17 standard. The results showed that the corrosion resistance of samples treated by QPQ was 16 times that of blackening, 6 times higher than that of zinc plating, 3 times more than that of chrome plating, and 2 times that of nickel chromium plating.
