摘要： A highly erosive and abrasive wear resistant composite coating system is described in which an intermediate layer of substantially pure tungsten is deposited on a substrate. An outer layer is then deposited comprised of a mixture of tungsten and tungsten carbide, with the tungsten carbide consisting of W.sub.2 C, W.sub.3 C or a mixture of both. The thickness of the intermediate layer is sufficient to confer substantial erosive and abrasive wear resistance characteristics on the composite coating system. The ratio of the thickness of the intermediate layer to the thickness of the outer layer is controlled and is at least above 0.30 in the cases of W+W.sub.3 C, W+W.sub.2 C+W.sub.3 C and W+W.sub.2 C coatings.

摘要： An improved highly erosive and abrasive wear resistant multi-layered coating system on a substrate which provides protection against impact of large particles is disclosed comprising a plurality of composite layers. In each of the composite layers, the first layer closest to the substrate comprises tungsten of sufficient thickness to confer substantial erosion and abrasion wear resistance characteristics to the coating system and a second layer deposited on the first layer comprises a mixture of tungsten and tungsten carbide and the tungsten carbide comprises W.sub.2 C, W.sub.3 C, or a mixture of both. Because the resulting coating system has enhanced high cycle fatigue strength over the substrate, the coating system is especially useful on such structures as turbine blades and similar articles of manufacture where such high stress cycles occur during normal operation. Also dislcosed is the method for preparing such improved composite coating systems.
