  • Ion carburizing
    Patent number: 5127967
    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.
    Type: Grant
    Filed: June 24, 1991
    Date of Patent: July 7, 1992
    Assignee: Surface Combustion, Inc.
    Inventors: Stephen H. Verhoff, Garrol Tackett
