Abstract
432,212. Coating with metals. RODRIGUEZ, A. O., Valverde-Leganes, Badajoz, Spain. Jan. 23, 1934, No. 2346. Convention date, Feb. 24, 1933. [Class 82 (ii)] A metallic coating free from pores, spots, &c., is obtained on ferrous metal articles by heating the articles in an atmosphere of reducing and decarbonizing gases or vapours in the nascent state, passing the articles through a bath of molten metal the surface of which is not in contact with the reducing and decarbonizing gases or vapours, and finally cooling and smoothing the coating. In the form shown an iron wire 7, which has previously been cleaned, for example by treatment with acid and alkaline solutions, washing, and drying, is drawn from a roll 8 and passed into a hollow tube 1 connected to a retort 9. The tube 1 may be so constructed that a plurality of wires, tapes, sheets, &c., may be treated simultaneously. The retort 9, the tube 1, and the coating pot 4 are located in a furnace and heated to about 500-700 C., Ammonium chloride is introduced into the retort 9 and the vapours formed pass into the tube 1 and react with the iron wire causing the formation of hydrogen and ammonia in the nascent state which combine with the carbon and reducible impurities on the wire, the resulting products being discharged in vapour form at the open end 12 of the tube 1. A mixture of ammonia and hydrochloric acid which react together to form ammonium chloride, may be introduced into the tube 1 instead of ammonium chloride vapours. The heated wire passes from the tube 1 into a bath 3 of molten aluminium, the metal being covered by a deep layer 13 of reducing or inert material which serves to protect the cleaned wire from oxidation and to prevent contact between the ammonium chloride vapours and the surface of the molten metal. Alternatively the bath may be covered with a thin layer of powdered or liquid reducing or inert material and the oxidation of the wire prevented by the vapours issuing from the tube 1. The coated wire is then passed through an opening 14 in a metal die 6, the heat radiating capacity of the die being such that a pasty mass of excess coating metal which exerts a cooling and smoothing action on the coated wire is maintained in the opening 14.
