Abstract: Provided is a carbon layer derived from carbide ceramics, wherein metal or non-metal atoms are extracted selectively from the surface of carbide ceramics to form voids, which, in turn, are filled with carbon synthesized by a carbon compound, thereby providing improved roughness and hardness, as well as to a method for preparing the same.
