摘要
通过生产中的试验例证和检验结果 ,针对《汽车渗碳齿轮金相检验》标准中“马氏体级别”的概念和评级方法进行了分析和讨论。认为不宜将“马氏体级别”
The concept and grading method of the“martensitic grade”in the standard of《Metallographic Test for Carburizing Auto Gear》were analyzed and discussed according to the experience and test results. It should be considered that it is not suitable to keep the“martensitic grade”as an independent quality index.
