Abstract

This invention relates to a method of improving the surface properties of a metal and the metal with a coating layer prepared by the same and in particular, to a method of improving the surface properties of a metal comprising the steps of providing a substrate comprising a single metal or alloy at its surface, preparing a powder for coating comprising one or two more single metals or the powder of the alloy for forming an intermetallic compound, which forms an intermetallic compound with the single metal or the metal element of the alloy, coating the prepared powder for coating onto the substrate by a cold spray method, and forming the intermetallic compound by the heat treatment of the coated coating layer and the substrate and the metal with a coating layer prepared by the same. In accordance with the invention, an intermetallic compound coating layer having superior surface properties can be formed by the improvement of the surface without causing damages such as heat distortation to a substrate during the formation of the coating layer, heat treatment within a short time at a low temperature is possible and thus manufacturing costs are decreased, and the occurrence of residual stress between the substrate and coating layer according to heat treatment can be minimized because the intermetallic compound is formed in the process of heat treatment.
