Abstract

Magnesium (Mg) alloys have been increasingly used in industries and biomaterial fields due to low density, high specific strength and biodegradability. However, poor surface-related properties are major factors that limit their practical applications. This paper mainly focuses on laser-based anti-corrosion technologies for Mg alloys, beginning with a brief review of conventional methods, and then demonstrates the feasibility of laser surface technologies including laser surface melting (LSM), laser surface alloying (LSA), laser surface cladding (LSC) and laser shock peening (LSP) in achieving enhancement of corrosion resistance. The mechanism and capability of each technique in corrosion resistance is carefully discussed. Finally, an outlook of the development of laser surface technology for Mg alloy is further concluded, aiming to serve as a guide for further research both in industry applications and biomedical devices.
