ABSTRACT:
A process and apparatus for coating conductive workpieces by ionized vapors with the assistance of a glow discharge includes providing a periodically pulsed input of energy for the discharge so that stress on the parts is reduced and a smooth coating results. Either a constant or periodic magnetic field is superimposed to influence the coating process for better results and better handling.
