ABSTRACT:
The method for producing the disclosed material comprises chemical vapor depositing on the substrate a substantially columnar, intermediate layer of tungsten and chemical vapor depositing on the intermediate layer a non-columnar, substantially lamellar outer layer of a mixture of tungsten and tungsten carbide. The tungsten carbide comprises W.sub.2 C, W.sub.3 C, or a mixture of both wherein the ratio of the thickness of the tungsten intermediate layer to the thickness of the outer layer is at least: (a) 0.35 in the case of tungsten plus W.sub.2 C in the outer layer, (b) 0.6 in the case of a mixture of tungsten and W.sub.3 C in the outer layer and (c) 0.35 in the case of mixtures of tungsten and W.sub.2 C and W.sub.3 C in the outer layer. The chemical vapor deposition steps are carried out at pressures within the range of 1 Torr to 1,000 Torr and temperatures within the range of about 300.degree. to about 650.degree. C.
