为了提高镁合金的耐腐蚀性能，人们尝试通过气相沉积技术在镁合金表面涂覆纯镁。在真空度为10 - 2 Pa的不锈钢管中，于1050 K下蒸发3 N-Mg和AZ 91 D合金，通过蒸馏效应提纯，并沉积在镁合金基体表面。AZ31 1.据认为，孤立的小颗粒的镁首先形成在基板上，然后它们生长具有多面的平面，以覆盖基板的表面。对AZ 31铝合金涂层和未涂层试样在1%NaCl溶液中进行了盐浸试验，结果表明涂层试样的耐盐腐蚀性能优于未涂层试样，具有上级耐蚀性。
In order to improve corrosion resistance of magnesium alloys, it has been attempted to coat the surface of the magnesium alloys with pure magnesium by vapor deposition technique. Commercial 3N-Mg and AZ91D alloy were evaporated at 1050 K in a stainless steel tube evacuated at about 10 -2 Pa, purified by a retort effect, and deposited on the surfaces of a substrate which was a magnesium alloy. AZ31. 1. It is considered that isolated small particles of magnesium are firstly formed on the substrate, and then they grow having faceted planes to cover the surface of the substrate. The coated and uncoated specimens of AZ31 ailoy were examined with salt immersion tests in 1% NaCI solution, which showed superior corrosion resistance of coated specimen to uncoated one.
