Abstract

A method for producing a hard deposit on a substrate is described wherein a volatile halide of tungsten or molybdenum is reacted with carbon monoxide and water vapor to effect the deposition on a substrate of a compound of the metal in a liquid phase. The liquid phase deposited on the substrate is then reacted to remove oxygen and halogen and produce a hard deposit containing the metal and carbon. Also described are products which may be producted by the above method.
