FIELD: process engineering.
SUBSTANCE: invention relates to production of protective coatings and can be used for making high-temperature furnace elements (heaters, holders) intended for carbon- or metal-thermal reduction of metals from their oxides. In compliance with this invention, carbon material with refractory metal carbide coating comprises carbon substrate and cover layer, mid layer of carbon and titanium carbide and variable-composition cover layer of titanium carbides and/or zirconium carbides laid over said mid layer. Proposed method comprises forming mid layer of ceramic slurry on carbon substrate composed of titanium oxide and vacuum oil and thermal treatment in atmosphere of hydrocarbons and inert gas at 1150-1250°C. Cover layer is formed by filling the titanium sponge or zirconium powder at 1700-1900°C in vacuum.
EFFECT: higher resistance to oxidation, cracking and destruction at high-temperature vacuum.
