摘　　要：不锈钢氮化后进行金相观察,发现都有黑色条纹。在解决清除"条纹"的过程中,对常规低温氮化的影响因素,进行了多方面的研究和生产验证。总结出有效的氮化工艺,氮化后试样的氮化层深、硬度、脆性等指标都达到工艺要求,同时在各种材料的金相试样上都未发现有黑色条纹。There are black stripe in the metallographic examination of stainless steel after nitriding. In the process of removing stripe, the influence factor of the conventional low temperature nitriding is researched and verified in production. The effective nitriding process is summaried, and nitriding depth, hardness and brittleness index of nitriding samples have reached technological requirements. At the same time, the black stripe do not find in the metallographic specimen of various materials.
