Claims9
A tantalum carbide coated carbon material comprising:
- a substrate;
- and
- a tantalum carbide film formed on the substrate,
- wherein a surface contact angle of the tantalum carbide film is 50° or more,
- wherein the tantalum carbide film has a thickness of 10 μm to 50 μm,
- wherein the tantalum carbide film includes X-ray diffraction peaks of (111), (200), (220), (311) and (222) planes as a main peak and a diffraction intensity ratio according to the following relation 1 is 1.8 to 2.5,
- I(111)/I(200)+(220)+(311)+(222)) [Equation 1].
