Surface protection of Mg alloys in automotive applications: A review

摘要: Mg alloys find widespread applications in transportation industries especially cars and trucks because of their edges light-weight design, which can greatly help improve the fuel efficiency decrease gas emissions vehicles; However, alloys’ high sensitivity to corrosive environments limit penetration automotive applications. Surface coating is one most effective economic ways protect from corrosion. Presently, currently researched commercial coatings that are specifically applied industry reviewed this paper. With some components subjected corrosion repeated load simultaneously, fatigue coated as well. Additionally, a part attention review given assessment approaches performance for purpose material/surface system selection. Finally, corrosion-related challenges growth alloys, future developments research directions on surface testing discussed.
