ABSTRACT

Magnesium alloys are low in density, high in strength and non-toxic, nevertheless, their industrial application is substantially limited owing to their low electrode potential and susceptibility to corrosion. Surface and coating technology is widely used to improve their corrosion resistance. Graphene is one candidate material for anti-corrosion coatings because of its high aspect ratio, outstanding chemical resistance and good physical resistance. Its good barrier properties mean that graphene may have a wide range of applications in magnesium alloy coatings. This paper reviews (i) the potential of graphene for anti-corrosion coatings, (ii) the production methods and types of graphene anti-corrosion coatings, (iii) their properties, (iv) the protection mechanisms and (v) the future development trends of graphene-based corrosion protective coatings on magnesium alloys.

摘要

镁合金密度低、强度高、无毒，但由于电极电位低、易腐蚀，其工业应用受到很大限制。广泛采用表面和涂层技术来提高其耐腐蚀性能。石墨烯因其高长径比、突出的耐化学性和良好的物理性而成为防腐涂料的候选材料之一。其良好的阻隔性能意味着石墨烯在镁合金涂层中可能有广泛的应用。本文综述了（i）石墨烯用于防腐涂料的潜力，（ii）石墨烯防腐涂料的生产方法和类型，（iii）它们的性能，
