Parametric Study of Laser Cladding of AS 21 Magnesium Alloy with Aluminium Silicon/Tungsten Carbide Powder

Magnesium alloys are of growing interest for a number of applications in a range of industries because of their low densities and high specific strength. An impediment to their increased application is their low resistance to both wear and corrosion compared to that of steel or aluminium alloys. This is due to their relatively low surface hardness and high chemical affinity for numerous elements respectively.
