Abstract:
A process of applying an electrode to a carrier of ceramic material, said process comprising the steps of:providing a tube-shaped carrier of ceramic material;supplying electrode material to a spray tube which produces a laterally directed spray of the electrode material;advancing the spray tube into the hollow space of the tube-shaped carrier along a longitudinal axis of the tube-shaped ceramic carrier while non-rotating and while spraying the electrode material to apply a lead-in conductive track of the electrode material on the inner side wall of the tube-shaped ceramic carrier; andsubsequently, rotating the tube-shaped ceramic carrier about its longitudinal axis relative to the spray-tube while continuing the spraying to produce a first ring-shaped electrode on the inner side wall of the tube-shaped ceramic carrier and in contact with the conductive track.
