Abstract

845,410. Coating with metals. UNION CARBIDE CORPORATION. July 5, 1956 [July 26, 1955; Oct. 11, 1955(2); Oct. 17, 1955(2)], No. 20815/56. -Class 82(2) [Also in Groups XI, XXII and XXIX] In a coating process an arc struck between a non-consumable electrode 302 and a consumable electrode 306 is passed together with a stream of gas through a constricted outlet 304 in a nozzle 303, the consumable electrode being a wire or strip continuously fed by rollers 308 to provide the coating material. A pilot arc is struck between the nozzle 303 and the electrode 302 which is either a tungsten or a watercooled copper electrode. The gas may be any of the usual shielding gases, e.g. argon, helium or hydrogen with, if desired, additional active agents, e.g. chlorosilanes. The arc current is A.C. or D.C. of either polarity. A separate current source 316 may be connected between the wire 306 and the work 315 to extend the arc to the work. The wire 306 may be plain or stainless steel, copper or aluminium, flux cored or coated or covered with carbides for hard surfacing. Brick, steel and aluminium workpieces are referred to. Specification 845,411 is referred to.
