TANTALUM CARBIDE-COATED CARBON MATERIAL AND MANUFACTURING METHOD FOR SAME

摘要

A tantalum carbide coating film (42) which covers a carbon substrate (41) is formed on the surface of the carbon substrate (41). The tantalum carbide coating film (42) has a maximum peak value of at least 80° in the (311) plane orientation of a diffraction peak corresponding to the tantalum carbide as determined by X-ray diffraction.
