Description

570°С и времени выдержки 8 ч иолучен диффузионный слой глубиной 0,55 мм с в зкой нитридной зоной глубиной 55 мкм при микротвердости кгс/мм.570 ° C and a holding time of 8 h. A diffusion layer of 0.55 mm in depth with a viscous nitride zone of 55 μm in depth with a microhardness of kgf / mm was obtained.

Пример 2. При азотировании в электромагнитном поле стали 38ХМ10А при температуре 570°С и времени выдержки 8 ч диффззионный слой 0,4-0,5 мм с в зкой нитридной зоной глубиной 25 мкм при микротвердости кгс/мм.Example 2. When nitriding in the electromagnetic field of steel 38XM10A at a temperature of 570 ° C and an exposure time of 8 hours, a diffusion layer of 0.4-0.5 mm with a viscous nitride zone of 25 μm in depth with microhardness kgf / mm.

Ускорение процесса газового азотировани  от посто нного действи  электромагнитного пол  объ сн етс  тем, что поле ориеитирз ет структуру ( вление магнитострикции), дела  ее более «рыхлой. Это способствует лучшему проникновению азота. Газова  фаза под действием электромагнитного пол  активизируетс , что з -скор ет процесс диффузии. При этом получаетс  нехрупкий нитридный слой.Acceleration of the gas nitriding process from the constant action of the electromagnetic field is explained by the fact that the field of orientation builds up the structure (magnetostriction), making it more "loose." This promotes better nitrogen penetration. The gas phase is activated by the electromagnetic field, which speeds up the diffusion process. This results in a non-friable nitride layer.
