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 International thermonuclear reactor (i.e. nuclear fusion) 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. A mixture 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 with thickness of about 1 mm were sprayed on graphite substrates with cylindric shape. Pure tungsten and pure ZrC were sprayed under similar conditions as the cermet. Microhardness, surface roughness, XRD, XRF, dilatometry and Raman microspectroscopy were used for the coatings characterization. ZrC coatings are hard and their elastic modulus is high. They can serve
