ABSTRACT A method is described for improving the erosion and abrasion resistance of a sharp edged metal structure. A base layer of a noble metal is formed on the surface of the body of the structure followed by a chemical vapor deposited outer coating comprising a mixture of tungsten and tungsten carbide. The tungsten carbide is selected from the group consisting of H2C, W3C, and mixtures thereof and is fine grained, non-columnar and having a substantially layered microstructure. Also described is a sharp edged metal structure formed by the method.
