A method of enhancing wear resistance of a metallic substrate includes applying a coating of an interstitial element to a surface of a substrate. A laser beam is directed onto a localized area of the metallic substrate coated with the interstitial element locally raising a temperature of the metallic substrate to a temperature causing the interstitial element to diffuse into the substrate. A layer of alloy including the interstitial element is generated onto the localized area of the metallic substrate. A focal point of the laser beam is disposed at a location spaced from the surface of the substrate for optimizing a power density of the laser beam at the surface of the substrate. The coating of interstitial element not diffused into the substrate is removed exposing the layer of alloy including the interstitial element. |
