摘要:: 基于渗氮层出现裂纹的原理，结合现有氮化罐老化、炉气压力不稳定等生产条件对渗氮层裂纹产生的原因进行了分析。通过对生产过程中的准备工作、炉气压力及退氮过程等可能导致渗氮层出现裂纹的各个环节进行严格控制，解决了目前生产中渗氮层裂纹的问题，提高了渗氮层的质量。

Abstract:: Based on the principle of crack appearing in nitrated layer, and combined with production conditions, such as aging of nitrating furnace, unstable gas pressure and so on, the cause of cracks in the nitrated layer is discussed. Through strict control of each link (such as preparation work, furnace gas pressure, denitrating process, etc) that may lead to crack in nitrated layer, the problem of crack
