SURFACE TREATMENT METHOD AND SURFACE TREATMENT DEVICE

There is provided a surface treatment method in which a processing gas (G2) is brought in contact with a heated processing object made of steel (P), an element in the processing gas (G2) is solid-solutionized, and thus a surface treatment is performed on the processing object (P). The processing obj...

Zusammenfassung:	There is provided a surface treatment method in which a processing gas (G2) is brought in contact with a heated processing object made of steel (P), an element in the processing gas (G2) is solid-solutionized, and thus a surface treatment is performed on the processing object (P). The processing object (P) is heated to a heating temperature (T1) in a vicinity of a processing temperature (T3) at which the surface treatment is performed by heating an atmosphere in which the processing object (P) is disposed. The surface treatment is performed by bringing the processing gas in contact with a surface of the processing object (P) while the processing object (P) which is heated is directly heated to the processing temperature (T3).
