Plasma Spraying of Refractory Cermets by the Water-Stabilized Spray (WSP) System
Original language description
Among important metal matrix composites are cemented carbides, predominantly tungsten carbide with cobalt binder. For high temperature applications, e.g., in nuclear or thermonuclear reactors technology, metals with a higher melting point, namely, tungsten, are preferred. Tungsten carbides with a decomposition temperature of 2785°C should also be replaced by, for example, ZrC. Bulk parts can be produced by powder metallurgy techniques but plasma spraying of cermets could be an interesting alternative. Amixture of W powder was prepared with 3 to 20 vol. % of ZrC. This feedstock having a spheroidal character was fed into the plasma of the water-stabilized plasma (WSP) gun by means of an inert gas carrier. Coatings of a thickness of about 1 mm were sprayed on various substrates, namely, graphite. Pure tungsten and pure ZrC were sprayed under similar conditions. Microhardness, surface roughness, XRD, XRF, dilatometry and spectroscopic techniques (Raman microspectroscopy) were used
