摘要
Based on the nitriding potential in the processing furnace calculated by the in-furnace nitriding potential calculator and the target nitriding potential, the introduction amount of the ammonia gas is changed while the introduction amount of the ammonia decomposition gas is kept constant, such that the nitriding potential in the processing furnace is brought close to the target nitriding potential.
