COATED MEMBER AND FABRICATING METHOD THEREOF

摘要

PURPOSE: A coated member is provided to improve surface roughness and reduce damage to a member during a process for forming roughness by forming roughness on the member made of an inorganic ceramic material while using silicon carbide whose hardness is higher than that of the inorganic ceramic material. CONSTITUTION: Roughness(110) is formed on the member(100) composed of the first inorganic ceramic material. A coating layer(120) is coated on the member including the roughness, composed of an oxide compound. The second inorganic ceramic powder with hardness higher than that of the first inorganic ceramic material is injected to the surface of the member to form the roughness.
