摘要
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 condition, 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.
