本文通过对渗碳件的金相观察和淬火后硬度曲线的分析,认为目前渗碳钢渗碳层的测量方法欠深度,妥,且缺乏合理性,为了同国际上检验渗碳件渗层深度的标准相统一,本文建议:以硬度法代替金相法测定渗碳层以表面渗碳层的有效硬化层深度作为测定依据。
In this paper, the metallurgical observation of carburized parts and the analysis of the hardness curve after quenching, the current carburizing steel carburizing layer measurement method is less depth, proper, and lack of rationality, in order to test with the international carburizing parts of the depth of infiltration This paper suggests: Hardness method instead of metallographic determination of carburized layer carburized surface layer of the effective hardened layer depth as the basis for determination.
