<p>To reliably bond in an alloyed state various kinds of metals on a surface of various base metals in a simple, easy and efficient manner. A metal surface treatment method includes: a shot-peening step of shot-peening a dissimilar metal particle (2) on a surface of a base metal (1), the dissimilar metal particle (2) being a metal particle different from the base metal (1), to provide a dissimilar metal film (3) on the surface of the base metal (1); and an electron beam irradiation step of irradiating the surface of the base metal (1) with an electron beam (4), the surface of the base metal (1) having been provided with the dissimilar metal film (3) in the shot-peening step, to bond the dissimilar metal film (3) and the base metal (1) together.</p> |
