The Method for Producing Tungsten Carbides

The present invention relates to new tungsten carbides which are doped with fluorine in an amount of up to 0.5 wt % and which can also be doped with fluorocarbon compositions.

These tungsten carbides are produced according to a new CVD method in which the phase contains tungsten hexafluoride, hydrogen and a carbon-containing gas. This method is characterised in that the carbon-containing gas is previously thermally activated. 

The tungsten carbide coatings can be applied onto construction material and articles made therefrom. These coatings exhibit a high wear and corrosion resistance as well as a high chemical stability.
