为了减少碳氮化铁层(ε-相)的脆性表面区,可在H_2—N_2气氛中进行退氮处理。在加有能降低氮势的气体的氨气气氛中,得到了较好的结果。这些研究是在华沙市精密机械研究所进行的。很清楚,在延长氮化过程时间的条件
In order to reduce the brittle surface area of the carbonitride layer (ε-phase), the nitrogen removal treatment can be performed in a H 2 -N 2 atmosphere. Good results have been obtained in an ammonia atmosphere with a gas capable of reducing the nitrogen potential. These studies were conducted at the Warsaw Institute of Precision Machinery. It is clear that the conditions for extending the nitriding process time
