摘要： PROBLEM TO BE SOLVED: To provide a sliding member which can prevent deformation of the raw material by cooling and occurrence of rust on the surface and suppress changes of the surface roughness, even in a long-time use.SOLUTION: A sliding member comprises a base material part 110 composed of a steel material, a nitrogen diffusion layer 120 which is formed on the front surface side of the base material part 110 and has a thickness of 10-50 μm and a nitrogen compound layer 130 which is formed on the front surface side of the nitrogen diffusion layer 120, has a thickness of 10-50 μm and serves as the outermost surface. The nitrogen compound layer 130 and the nitrogen diffusion layer 120 are formed by carrying out, in order, a first heating step of heating a raw material composed of a steel material in an ammonia atmosphere of 570-660°C, a second heating step of heating the raw material in a non-oxidative and non-ammonia atmosphere of a temperature, in a range of 660-690°C, higher than the temperature of the first heating step and an oil cooling step of carrying out oil cooling at an oil temperature of 60-80°C, after the second heating step.

摘要： PROBLEM TO BE SOLVED: To provide a sliding member and a clutch plate in which deformation of materials caused by cooling is suppressed and rust formation on surfaces is prevented, and methods for manufacturing the same.SOLUTION: The sliding member includes: a matrix material part 110 made of steel; a nitrogen-diffused layer 120 with a thickness of 20-50 μm formed on the front face side of the matrix material part 110; and a nitrogen compound layer 130 with a thickness of 20-50 μm that is formed on the front face side of the nitrogen-diffused layer 120 and serves as the outermost layer. The nitrogen compound layer 130 and the nitrogen-diffused layer 120 in the sliding member are formed through: a heating step of carrying out a heat-treatment of a material made of steel in an ammonia atmosphere at 660-690°C; an oil cooling step of carrying out oil cooling at an oil temperature of 60-80°C after the heating step; and a tempering step of carrying out a tempering treatment while applying pressure onto the surface at 250-350°C after the oil cooling step.
