Abstract

Metallic coatings are produced from metals vaporized by an electric arc in a chamber supplied with air or gas under pressure, the vaporized metal being removed through a hollow electrode. The metal to be deposited may itself form one or other of the electrodes or it may be supplied thereto in the form of wire or powder. The materials fused or vaporized may consist of hard metals such as tungsten, zirconium, tantalum, or lighter metals such as aluminium and its alloys, metals such as nickel, chromium, cobalt, iron, or steel and also carbides of metals such as tungsten, chromium, molybdenum, tantalum, titanium, niobium, vanadium, zirconium; silicides, nitrides, or phosphides of hard metals may be used in conjunction with metals fusing at lower temperatures, such as metals of the iron, copper, or zinc groups such as iron, cobalt, nickel, rhodium, copper, zinc, cadmium, antimony and bismuth. The electrode may be formed from the material fusing at the higher temperature while the other metal is added as a wire or powder.
