Abstract

220,928. Baints, H. V. Aug. 24, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Drawings to Specification. Pens.-Steel, copper, aluminium 'bronze, and other metals are provided with a thin, strongly adhering coating of tungsten or other refractory metal of the tungsten group by heating, electrically or otherwise in an atmosphere of a volatile compound of the refractory metal (such as WCl6 or WOCl4) and an excess of dry hydrogen. Tungsten coated pens may substitute iridium-pointed gold pens. The tungsten coating may be applied to the articles as stated above, or the articles, after pickling, may be coated with a tungsten paste of the kind used for incandescent lamp filaments, into which may be introduced thoria or nickel, the coated article being then dried and heated strongly; or the 'tungsten coating may be applied electrolytically.
