The dyeing of magnesium alloy using short pulse laser was studied. The laser-irradiated part could be dyed with reactive dye, which had sufficient dyeability. On the laser-irradiated surface, the layer of fine particles was formed, and the surface free energy was greatly increased. In addition, chromium contained in the dye was detected only in the layer of fine particles. From these results, the dyeing in this process was considered to be based on the increase of surface free energy and the change of surface condition caused by the formation of the layer of fine particles.
