[PROBLEMS]To reliably bond various metals onto a surface of various parent metals in an alloyed state in a simple, easy and efficient manner.[MEANS FOR SOLVING PROBLEMS]A metal surface treatment method comprising a shot peening step of shot peening dissimilar metal particles (2), which are different from a parent metal (1), on the surface of the parent metal (1) to provide a dissimilar metal film (3) on the surface of the parent metal (1), and an electron beam irradiation step of applying electron beams (4) to the surface of the parent metal (1) with the dissimilar metal film (3) provided thereon by the shot peening step to bond the dissimilar metal film (3) and the parent metal (1). |
