摘要： PROBLEM TO BE SOLVED: To execute efficient and uniform roughening free from deterioration in the characteristics of the material to be applied with coating by executing roughening treatment using a laser beam to the surface of a hard inorganic material as a surface layer, particularly, on the surface of a material with a crystal structure having covalent bondability to form coating by a thermal spraying method. SOLUTION: Prior to the formation of coating on a surface layer composed of a hard inorganic material, the surface of the material to be subjected to coating (hard inorganic material) is subjected to roughening treatment. In accordance with the degree of the objective roughening, the spot diameter, focal distance, pulse frequency or the like of a laser beam 5 are regulated, which is applied to the surface layer 2 of the material to be subjected to coating, and boring or grooving is executed. Substantially, it is applied to the one in which a surface layer composed of a hard inorganic material such as Sic, TiC, TiN, HfC or the like is formed on a material composed of a hard inorganic material such as Sic, TiC, HfC or the like, or a WC/C composite material or a base material such as graphite or the like.

摘要： PROBLEM TO BE SOLVED: To provide a method for forming an SiC coating layer in an oxidation resistant treatment of a carbonaceous raw material, suitable for treating a large-sized mass production product, excellent in adhesion property of an Si source with the raw material under a heat treatment, and not generating a blister and a distortion at the surface of the raw material. SOLUTION: This method of an oxidation resistant treatment of a carbonaceous raw material is to react carbon on the surface of the carbonaceous raw material with silicon for converting the composition of the surface of the carbonaceous raw material to silicon carbide (SiC). In this case, as a source 11 (Si source) for supplying Si necessary for the reaction, a powder of a material containing silicon added with a powder of a ceramic material and further added with a thermosetting resin 12, is used. Also, characteristics of the process are: using a method of applying the powder instead of using a crucible treatment and using a raw material powder consisting of an oxide as a powder of the ceramic material and a powder of silicon nitride (Si3 N4 ) as the Si source.
