Abstract

884,797. Coating with metals, deposited electrophoretically. BRITISH IRON & STEEL RESEARCH ASSOCIATION. May 16, 1960 [May 22, 1959], No. 17501/59. Class 41. A coating of metal is formed on a metal surface by depositing the coating metal by electrophoresis from a suspension of the finelydivided metal in an organic liquid, and then heating the coating to remove the liquid and consolidate the coating which may form an alloy with the substrate metal. Finely powdered Al, Sn, Fe or alloys of 1-10 microns particle size are suspended in a polar solvent, e.g. denaturated alcohol, together with a small amount of tannic acid and salts of the metal being deposited to act as conductor, e.g. AlCl 3 and Al(NO 3 ) 3 in the case of powdered Al. The substrate metal may be iron, steel, or copper and is pre-treated with NaOH, HC1, washed and dried. An undercoat of indium may then be applied. In a suitable apparatus, a cleaned low carbon steel strip 15, passes over a conductor roll 1 and under an insulated sink roll 2 immersed in a shallow tank 3 containing the electrophoretic bath. A deposit of aluminium is formed on both sides of the strip at a C.D. of L.A.S.F., passing between aluminium anodes 4, 5. The coated strip emerges and is supported by a second conductor roll 7, while passing through a drying chamber 6, where the alcohol is vaporized and recovered. The coated strip then enters a rolling mill 9 which may be heated to partly consolidate the coating, and is then fully heat-treated and annealed in a lead bath 11 at 350‹ C., a tower 12 containing a reducing gas and maintained at 700‹ C., where after 0.3 to 1 sec. treatment the coated strip enters a second lead bath 13 at 350 ‹ C. After cutting and coiling the strip is maintained at 250‹ to 450‹ C. for 15 to 30 minutes, when the coating is sintered, fully bonded and annealed. There may be a further step of heating to a subcritical annealing temperature of the steel and rapidly quenching to an age-softening temperature as described in Specification 877,793. The process may be applied to iron, steel or copper as sheet, strip wire, or articles.
