In recent years, from viewpoints, such as energy saving and economical efficiency, in order to make a product light, the products which use aluminum for part material are increasing in number, and it is thought that this tendency also continues from now on. However, it has the fault that hardness of aluminum is low and the surface tends to get damaged compared with iron base material. Then, in this research, production of surface modificated layer was tried on the aluminum alloy (A5083) surface part by irradiating YAG laser beam, after sticking stainless steel powder to the surface. Consequently, thick surface modificated layer was able to be obtained by the high hardness which a crack does not occur.
