摘要： PROBLEM TO BE SOLVED: To provide a nitride film which has a high nitride content and is thick and dense, and to provide a method for easily forming the nitride film on a substrate.
SOLUTION: The method for forming the nitride film includes thermal-spraying a mixture substantially composed of a powder of a metallic element or a non-metallic element, which is a raw material for thermal spraying, and a powder of the nitride of the element. The method inhibits a nitriding reaction between element powders and the coagulation of the powders due to consequent crystal growth, by the existence of the nitride powder, and as a result, can easily provide the dense and thick nitride film. The film-forming method also includes previously mixing the nitride powder, thereby increases a nitride content in the film and simultaneously relatively decreases a ratio of an unreacted element powder, and consequently provides the thick film with the high nitride content.

摘要： PROBLEM TO BE SOLVED: To provide an iron nitride film formed through a thermal spraying process, and to provide a manufacturing method therefor. SOLUTION: The thermal-sprayed film mainly containing iron nitride is formed on a substrate, by charging iron in thermal plasma while contacting a strongly luminant part of the thermal plasma containing nitrogen with the substrate, in the thermal spraying process. In the above step, it is recommended to form the thermal-sprayed film while keeping the temperature at the part to be film-formed to the decomposition temperature of iron nitride or lower, by controlling the temperature of the substrate. Furthermore, it is possible to form a dense thermal-sprayed film with a high content ratio of iron nitride even when iron remains in a gap between iron nitride particles in the thermal-sprayed film, by proceeding nitriding of iron through irradiating the substrate with thermal plasma without charging iron while contacting the strongly luminant part of the thermal plasma containing nitrogen with the substrate, and keeping the temperature at the part to be film-formed to the decomposition temperature of iron nitride or lower.
