ABSTRACT:
A heat treat process is disclosed for use in an ion glow discharge chamber for carburizing ferrous workpieces. The process provides rapid carburizing cycles by optimizing the power supplied to the glow discharge correlated to temperature and desired uniformity of the carbon gradient profile while also optimizing the mass flow of the substantially pure carbon bearing gas which is correlated to the desired uniformity of the carbon gradient profile.
