ABSTRACT OF THE DISCLOSURE In this method for forming an alloy layer on the surface of an aluminum alloy substrate, a powder for alloying, containing a substance to be alloyed with the substrate and an element selected from the group consisting of silicon and bismuth, is disposed upon the surface of the aluminum alloy substrate. This powder is then irradiated with a CO2 laser, so as to be melted and fused together with a surface portion of the aluminum alloy substrate, so that these two are alloyed together. The powder for alloying may be a powder of an alloy of the substance to be alloyed with the aluminum alloy substrate and the element selected from the group consisting of silicon and bismuth, or alternatively may be a mixture of a powder of the substance to be alloyed with the aluminum alloy substrate and a powder of the element selected from the group consisting of silicon and bismuth.
