Abstract:
A method for producing a carburized part by carburizing a steel member under a vacuum in a decompression furnace while feeding carburizing gas comprises a step for forming an oxide film on at least a part of a surface of the steel member, a step for generating carbon by reducing the oxide film with the carburizing gas, and a step for carburizing the surface of the steel member under a vacuum by diffusing the carbon.
