Research progress of laser surface modification of magnesium alloys

Magnesium and its alloys have excellent physical and mechanical properties for a number of applications such as: automobile, aerospace, and electronics. However, the poor corrosion and wear resistance limits widespread applications. Laser surface modification, including laser surface melting (LSM), laser surface alloying (LSA), and laser surface cladding (LSC), have been the subject of considerable interest as a means of improving the corrosion and tribological properties of magnesium and its alloys. The aim of this report is to review the recent progress in laser surface modification of magnesium alloys. The problems to be solved and the prospects of laser modification of magnesium and its alloys are discussed.
