为解决镁合金在工程应用过程中的腐蚀问题，按照工况条件制作了镁合金试验件，并在试验件上分别制备了微弧氧化电泳层和微弧氧化电泳有机涂层。通过试样的盐雾试验和静载试验，得出下述结论：微弧氧化电泳层在不被破坏的前提下，可以保护镁合金不受腐蚀；但在工况条件下，由于过盈配合等原因，不可避免地会破坏微弧电泳层，导致镁合金腐蚀。研究表明，在微弧氧化电泳层上制备有机涂层，既能有效保证微弧氧化电泳层不被破坏，又可在实际工况条件下保护镁合金不受腐蚀。

To solve the corrosion of magnesium alloy in the engineering application,the paper imitated the working con-dition,made magnesium alloy parts,and prepared micro-arc oxidation layers and micro-arc oxidation electrophoresis layers on the parts.Salt spray tests and static load tests showed that micro-arc oxidation layers can protect magnesium alloy from corroding on the condition that micro-arc oxidation layer is unbroken,but on normal working condition,it is inevitable to keep micro-arc oxidation layers unbroken.Preparing organic coating on the micro-arc oxidation electrophoresis layers can not only protect micro-arc oxidation layer from destruction,but also can protect magnesium alloy from corroding.
