Abstract Light metal materials such as aluminum and magnesium alloys are widely used in the field of transportation equipment where weight reduction of mechanical parts is required. However, it is known that wear resistance of light metals is lower than that of steel materials. Therefore, surface modification is being attempted by various coating techniques. In the present study, to improve the surface characteristics of corrosion resistance and wear resistance of light metals, surface modification was performed by bonding laminated sheet with ceramic powders and resin sheet to magnesium alloy using shot peening. The bondability of the laminated sheet was examined. Wear resistance was also evaluated. The laminated sheet could be bonded without peeling from the substrate. Bonding of hard powders was effective in improving wear resistance.
