Abstract

A body containing 40-99.5% volume of carbon or graphite and 60-0.5% volume of at least one of the carbides of Be, B, Si, Ti, Zr, V, Nb, Ta, Cr, Mo, W, Th and the rare earth elements is coated with one or more of these carbides. An outer layer comprising the metallic element or elements, or the oxide, silicide, nitride or boride of the metallic elements of the carbide component may be formed. The coatings may be applied by the application of molten material by dipping, plasma arc spraying, by painting, lacquering, impregnation or by the decomposition of volatile compounds of the required coating material. In the examples the following substrates are coated: C/ZrC, C/SiC, C/TiC and C/NbC; a ZrC coating is formed by plasma arc spraying Zr and converting to ZrC by heating in CO at 1600 DEG C.; SiC coating is formed by thermal decomposition of H3CSiCl3; TiC/WC coating by thermal decomposition of Ti and W chlorides in propane; NbSi by plasma arc spraying. The SiC coating may be heated in wet argon to form silicon oxide and the NbSi coating may be fused to form NbC, and SiC.ALSO:A body containing 40-99.5% volume of carbon or graphite and 60-0.5% volume of at least one of the carbides of Be, B, Si, Ti, Zr, V, Nb, Ta, Cr, Mo, W, Th and the rare earth elements is coated with one or more of these carbides.
