  • Process for forming a metal or alloy layer on an electricity-conducting work piece and device for executing same
    Patent number: 4321126
    Abstract: A device for coating a metal or alloy layer onto an electrically conducting workpiece comprises a low pressure chamber having a workpiece support platform mounted therein. An ion producer is connected to the chamber and adapted to receive an ionized carrier gas and spender medium. An electrode of first polarity is connected to the chamber and ion producer. An electrode of opposite polarity is connected to the support platform. Arc discharge means extend into the chamber and a turbulence chamber communicates with the low pressure chamber for creating turbulence in the carrier gas.

  • Process for forming a metal or alloy layer and device for executing same
    Patent number: 4288306
    Abstract: A process for depositing a metal or alloy layer on an electrically conductive work piece by means of a glow discharge. The work piece is inserted as one electrode of an electric field in a low-pressure chamber charged with a preionized carrier gas and coating material or spender medium. An arc discharge is utilized for explosively spattering the spender medium.
