针对ZG0Cr18Ni9Ti不锈钢悬挂座铸件在使用过程中发生的锈蚀现象,利用极化曲线方法分别对表面处理状态不同的试样进行试验,试验结果表明经达克罗表面处理的试样耐蚀性高于经酸洗钝化表面处理的试样。
Aiming at the corrosion phenomenon occurred in the process of using ZG0Cr18Ni9Ti stainless steel suspension seat castings, the polarization curves were used to test the specimens with different surface treatments. The results show that the corrosion resistance of the specimens treated with Dacromet surface is higher than that of Pickling passivation surface treatment of the sample.
