Abstract
404,972. Electrodeposition of metals. COLES, S. O. COWPER-, and FERBRITE, Ltd., Rossall House, Thames Street, Sunburyon-Thames. May 26, 1932, No. 14917. [Class 41.] Detached metal plates or sheets are mechanically conveyed through an electrodeposition bath at such a speed that the interval between immersion and emergence of any point of a plate or sheet does not exceed one minute and is preferably less than half a minute ; a currentdensity of at least 200 amps per sq. foot is employed. Electrical contact is made with the plates by means wholly external to the bath such as feed-rollers. As an example, a sheet measuring 28 inches by 20 inches may be passed through the bath in 4 seconds. The feed rollers are so arranged that a sheet is engaged by a fresh pair before release by the preceding pair. The position of the rollers may be adjusted. Anodes of lead or ferrosilican may be employed. The invention is particularly applicable to the coating of iron or steel plates with zinc or zinc alloys. The plates may be passed through a succession of depositing baths and may be subjected between successive baths to mechanical treatment such as abrasion or burnishing by transversely reciprocating brushes. The deposit may be consolidated by rolling preferably by a succession of lightly loaded rollers. The feed-rollers may be employed for this purpose. The rolling in the case of zinc may be carried out at a temperature of 80-100‹ C. and the rollers may be heated for this purpose. Before plating the plates are pickled by cathodic treatment in hydrochloric or sulphuric acid. The plating electrolyte is circulated through a filtering tank containing ground coke or silica and a regenerating tank containing scrap or granulated zinc, zinc residues or zinc oxide. A group of cells may be connected to a single filtering and regenerating system. The coated plates may be corrugated or may be further coated by enamelling or the like or by electrodeposition of rubber.
