APPARATUS FOR AND METHOD OF ELECTROPHORETIC COATING OF CATHODE SHAFTS WITH AN EMISSIVE LAYER |
摘要 |
It is possible to electrophoretically coat cathode shafts with an emissive layer having excellent mechanical properties by means of a device which comprises an electrophoresis bath and a jig which can be dipped therein and in which cathode shafts can be placed, which jig is composed of a plate of insulation material which is provided on the two surfaces with a first and a second electrically conductive layer, said jig having a large number of apertures in each of which a cathode shaft can be provided in a fitting manner such that each cathode shaft electrically contacts the first electrically conductive layer, and the plate is such a thickness that the side of the shaft to be coated is located at a distance from the second conductive layer, which distance is small in relation to the thickness of the jig, which jig is provided at least with a sealing non-electrically conductive layer on the side of the first conductive layer. |
