  • Carbon material coated with tantalum carbide
    Patent number: 11279620
    Abstract: The present invention relates to a carbon material coated with tantalum carbide and, more specifically, to a carbon material coated with tantalum carbide, comprising: a carbon substrate; and a tantalum carbide coated surface formed on the carbon substrate, wherein the carbon material coated with tantalum carbide has, as main peaks, X-ray diffraction peaks of the (111) plane, the (200) plane, the (220) plane and the (311) plane, of the tantalum carbide coated surface, and the peak of the (111) plane among the peaks has the maximum diffraction intensity. The present invention can provide the carbon material coated with tantalum carbide, having excellent chemical and physical resistance and extended lifespan.
