Abstract:

A refractory metal carbide coating is electrodeposited onto an object, using a bath containing an alkali fluoride melt, an alkali carbonate dissolved in the melt, a refractory metal-containing compound also dissolved in the melt, and an anode composed of that refractory metal. The object to be coated is immersed into the bath as the anode, and a voltage is applied until the coating obtains the desired thickness. By this process, coatings such as tungsten carbide and tantalum carbide having a desired stoichiometric composition may be deposited on the surface of an object. Author
