酸斑

对钛及钛合金板材表面酸斑的探讨

Discussion on Etching Trace on Plate / Sheet Surface of Ti and Ti Alloy

结果表明：板材表面存在的“酸斑”现象是可以预防控制和妥善解决的。

Our conclusion is that the " etching trace " on the sheet surface can be preventive controlled and properly settled .

前言：钛及钛合金薄板在经过碱、酸洗工艺处理后，经长时间放置板材表面经常会出现“酸斑”现象。

After being chemically processed and laid-aside for a long time , some sheet surface of Ti and Ti alloy would suffer from " etching trace " .
