Basic Issues on the Corrosion and Control Technologies of Magnesium Alloys
Poor corrosion resistance is a bottleneck problem that restricts the wide application of magnesium alloys. The corrosion pain points in the Mg industry include galvanic corrosion of magnesium alloy connectors,easy corrosion after sur-face protective coatings being damaged,and corrosion of magnesium alloys under force/chemical interaction. The reasons behind these corrosion pain points are analyzed,and the scientific problems about the corrosion of magnesium alloys are proposed,including the control steps of electrochemical corrosion,the galvanic corrosion law under multi-factor cou-pling,the corrosion mechanism under force/chemical inter-action,the construction and response mechanism of low-cost protective coatings. Based on the comprehensive considera-tion of the corrosion problems of magnesium alloys from the aspects of corrosion mechanism→materials→service envi-ronment→processing→service performance→surface protection→methodology,the corrosion mechanism of magnesium alloys is clarified,and the low cost,high corrosion resistance and multi-functional protective coatings are developed to promote the wide application of magnesium alloys.
