- CVD process;
A new chemical vapor deposition process has been developed to deposit hard coatings, containing tungsten carbide, at temperatures below 500°C. These coatings, which have been applied to both ferrous and nonferrous alloys, exhibit excellent resistance to wear and erosion. The coatings comprise a mixture of tungsten as well as the tungsten carbide, the latter being present as W2C, W2C+W3C, or W3C. The coatings'composition and properties can be controlled by varying the CVD process parameters. The unique lamellar, fine-grained microstructures of these coatings contribute to their excellent tribological properties.
