ABSTRACT:
The surface of a base metal is alloyed with the aid of a laser or electron beam which locally melts the surface. During the alloying, defects are prevented from occurring due to the use of an deoxidizing agent and a low-melting-point metal having a lower melting point than than of the base metal.
