In seawater and fresh water, aluminum alloy was not corroded as the all protection of alclad. In salt lake, the alclad on LC4 aluminum alloy remaindered for half a year, and used up for one year. The base of LC4 aluminum alloy was corroded seriously.

在海水和淡水中，包铝层可以对铝合金基材起到完全的保护作用，使基材免遭腐蚀；而在盐湖水中，半年时LC4铝合金表面尚有包铝存在，而一年时LC4铝合金表面包铝已完全消耗至尽，LC4的基体发生严重腐蚀。

According to SEM observation, the corrosion regulation of LC4 aluminum alloy with alclad in China water system and the protection of alclad on LC4 were studied. The corrosion experiment was done in seawater of Qingdao, Zhoushan, Xiamen, salt lake with high salinity of Geermu, and fresh water of Changjiang River in Hankou.

利用带包铝LC4铝合金在东部地区海水、西部地区盐湖水、中部地区淡水中的暴露腐蚀试验，对盐湖水中包铝对铝合金基体的保护作用行为进行了探讨，得到带有包铝的LC4铝合金在水系统中的腐蚀规律。

The results show that the samples exposed to the air previously for 24 h can be passivated automatically in acetic acid solution with Cl- with the corrosion potential remaining 100mV.No such phenomenon was observed for samples which were cathodically polarized with the corrosion potential stabilizing at a value of -242±3mv. The passive film formed by anodically polarizing is more proof than formed in the air.

研究还发现：在空气中放置24小时后的试样在Cl-醋酸溶液中能自钝化，自腐蚀电位为100mv；经阴极极化后的试样在Cl-醋酸溶液中不能自钝化，其自腐蚀电位为-242±3mv；经阳极极化形成的钝化膜比在空气中自然形成的钝化膜更致密。

Therefore, it is very important to improve the anticorrosion performances of magnesium alloys in industrial applications.

因此，在工业上应用中，使镁合金不易腐蚀（直译为：提高镁合金的反腐蚀能力），变得很重要。
