Abstract
The present invention is related to the method for surface-alloying comprising the steps of: (a) plating alloying ingredients on the surface of metal or alloy substrate to form plated layer, and (b) melting this surface using a laser beam to form an alloyed layer of which composition is different from that of base material. And, the method of this invention may further include surface-reforming method of metal or alloy substrate. And the method of this invention may further include surface-repairing method of damaged metal or alloy substrate. Using the method of this invention, an alloyed layer, which has improved resistance to grain boundary related material degradation phenomena, e.g. stress corrosion cracking, abrasion, fatigue, erosion, and so on, can be formed.
