Harvey process

A process for hardening the face of steel, involving the additional carburizing of the face of a piece of low-carbon steel by subjecting it to the action of carbon under long-continued pressure at a very high heat, and then to a violent chilling, as by a spray of cold water. This results in a thick surface of extreme hardness supported by material gradually decreasing in hardness to the unaltered soft steel at the back.
