Abstract: In a device for glow potential processing the metallic workpieces are placed on an electroconductive charging plate. The device has an oven located within a chamber that can be evacuated. At least three supports of the charging plate are arranged in the inner space of the oven and a supply line for the electric connection of the charging plate opens into a glow potential. The supply line is composed of at least three support insulators that end below the charging plate. The supports or the at least three support insulators can be lifted and lowered, so that the charging plate rests on the supports only or on the support insulators only.

Abstract: An apparatus for the treatment of a metallic workpiece includes (a) a transport structure which includes a mounting portion and a platform portion, the platform portion, which is the part of the transport structure on which the workpiece to be treated is positioned, being electrically insulated from the mounting portion, and (b) a hollow furnace which includes heating elements and two spaced apart electrodes, the furnace being constructed to allow the platform portion of the transport structure to be located within the hollow furnace during its operation while the mounting portion remains exterior thereto.
