用闭塞电池研究7075T6合金在EXCO溶液中的腐蚀行为

Study on Corrosion Behavior of 7075T6 Al Alloy in EXCO Solution with Occluded Cell

用模拟闭塞电池法研究了7075T6合金在EXCO溶液中的腐蚀行为。结果表明，模拟闭塞电池法可用来研究铝合金的局部腐蚀机理，在闭塞电池内外，铝合金的腐蚀行为有很大差别。

The corrosion behavior of 7075T6 aluminuium alloy in EXCO solution was studied by occluded cell method. Results indicatedthat the corrosion behavior was quite different between inside the occluded cell and outside the cell, and the localized corrosion mechanism of Al alloy was revealed deeply by occluded cell method.
