This study fabricated alloy films with excellent corrosion resistance by depositing an Mg film on Al-Si coated steel sheets and applying heat treatment. The fabricated Al-Mg-Si alloy film formed a corrosion product film composed of two layers, showing an excellent barrier effect against corrosion factors. The Mg in the film fabricated by heat treatment for 5 min was widely distributed in a dissolved state on the AI phase and was continuously involved in the corrosion product formation reaction. The corrosion resistance evaluation results were explained by analyzing the properties of the alloy film and the mechanism of forming corrosion products.

PVD镁涂层热处理形成的钢板上Al-Mg-Si膜的超高耐蚀性

本研究通过在 Al-Si 涂层钢板上沉积 Mg 膜并进行热处理，制造了具有优异耐腐蚀性的合金膜。制备的Al-Mg-Si合金膜形成了两层腐蚀产物膜，对腐蚀因素表现出优异的阻隔作用。热处理5 min制得的薄膜中的Mg以溶解状态广泛分布在Al相上，并不断参与腐蚀产物的形成反应。通过分析合金膜的性能和腐蚀产物的形成机理，解释了耐蚀性评价结果。
