Improvements in strength and wear resistance of mechanical components by adhering an alloy

摘要

The strength and wear resistance of a steel component is improved by adhering to it a material of higher strength compatible metal alloy. Preferably the higher strength material comprises a precipitation or age hardenable alloy such as Inconel (RTM) 725, which may be deposited by welding, plasma spraying, dip coating or electroplating. The component may then be subjected to a heat treatment regime which simultaneously softens the heat affected zone and hardens the higher strength material.
