Abstract
Powder of an alloy of tungsten carbide, vanadium carbide, vanadium, and a metal such as cobalt, nickel, iron, or manganese, with or without titanium carbide, may be mixed with diamond dust, formed into grinding wheels, drills, and the like, and sintered.ALSO:A hard alloy for tools, dies, ignition contacts, and other purposes consists of tungsten carbide containing up to 2,5 per cent of vanadium carbide, with or without titanium carbide, and a bonding medium consisting of an alloy of vanadium, with one or more lower melting point metals such as cobalt, nickel, iron, or manganese. The alloy may be made by adding to a mixture of ammonium vanadate, titanium oxide, and tungsten sufficient carbon to reduce the compounds and to form the required carbides of titanium, vanadium, and tungsten, and heating in hydrogen at 1800 DEG C.; the product is powdered, reheated at 1800-2000 DEG C., mixed with vanadium powder or vanadium compounds and an oxide of a metal such as cobalt, and reduced in hydrogen at 350-400 DEG C. The resulting alloy is ground and ball-milled and the powder is pressed to the desired shapes and sintered. The powder before pressing may be mixed with diamond dust and formed into grinding wheels, drills and the like.
