Abstract
The strength and wear resistance of a steel component is improved by adhering to it a material of higher strength compatible metal alloy, such as Inconel (RTM) 725 or like precipitation or age hardenable alloy. The higher strength alloy may be adhered by welding, plasma spraying, dip coating or electroplating. The component may be subjected to post-deposition heat treatment which preferably simultaneously softens a heat affected zone in the component and hardens the higher strength material.
