The object of the process is to reduce the carbon level via oxygen decarburization withoutchromium loss occurring.

此过程的作用是在不损失铬的条件下通过氧气降低含碳量。

This is the reason that the blue white passivating film is too thin.So,in order to settle the problem,a kind of process to acquire compare thick passivating film,high corrosion resisting WX-3TC trivalent chromium blue white desensitizer and its means were successfu...

为此，在增加蓝白色钝化膜的厚度方面进行了努力，终于研制成功了一种能获得较厚、具有高耐蚀性钝化膜的WX-3TC三价铬蓝白色钝化剂及其钝化工艺，盐雾试验出现白锈的时间可达240h以上，从而解决了蓝白色钝化膜耐腐蚀性差的难题。

So, in order to settle the problem, a kind of process to acquire compare thick passivating film, high corrosion resisting WX-3TC trivalent chromium blue white desensitizer and its means were successful obtained. The white rust appears after 240h in salt spray test, thus the poor corrosion resistance of blue white passivating film can be settled.
