Abstract

259,900. Siemens & Halske Akt.- Ges. Oct. 17, 1925, [Convention date]. Chromium, depositing; moving electrodes; electrolytes, circulating. - In the deposition of chromium or the interior of a tube 3 connected as cathode and located within a stationary electrolyser 1, the internal anode 4 is moved vertically relatively to the tube by means of a wire 9 which also serves as an electric connection. In the apparatus shown, an external anode 5, similarly movable, is provided for external coating. The anodes are provided with insulating beads or projections 11. The length of the anodes is about one-tenth that of the tube 3. At starting they are let down till their lower edges coincide with that of the tube and electrolyte is introduced to a level just above the upper edge of the anodes. The current is then turned on and the anodes raised at a uniform speed by hand or by clockwork, electrolyte being introduced by a cock 13 so as to be always just above the anodes. This procedure is necessitated by the use of an electrolyte which attacks metals in the unpolarized condition. The tube 3 may be supported by wires which also serve as electric connections.
