Abstract

552,388. Coating with metals. HATFIELD, H: S. July 31, 1941, No. 9722. Drawings to Specification. [Class 82 (ii)] [Also in Group XI] The surface of a body, e.g. of iron or steel, is coated with a thin layer of another material, e.g. tungsten or other hard metal or a carbide by subjecting the surface for a short time to heating caused by the impact of a focussed beam of high-speed electric particles, the coating substance being applied to the surface during and/or before the heating. The added substance may be applied as a powder coating, or may be fed mechanically into the beam. Metal may be coated with tungsten or alloyed with it, and carbon powder applied to form the carbide. A " hot cathode "or" cold cathode "apparatus may be employed. In the former, the filament is enclosed in a metal bell having in its centre a small perforated vessel containing tungsten carbide which is fed into the beam by vibration. The apparatus may be provided with timing devices to limit the duration of the heating and with means for subjecting a succession of parts to treatment. The focussed beam may be made to scan the surface treated.
