1960年,上海机械厂創造了“603无毒渗碳剂”,但在当时使用中渗碳件表面的碳濃度一般只能达到0.6～0.7%范圍,不能稳定在0.8～0.9%。为此,我所对不同規格的603渗碳剂和渗碳盐浴以及使用工艺作了有系統的試驗研究,两年多来經过100多炉次的試驗,对下列三个問題初步得到解决:(1)603渗碳剂本身的质量問題;(2)渗碳盐槽的中性盐成分和质量对渗碳結果的影响;(3)渗碳过程的工艺規范对渗碳层质量的影响。
In 1960, Shanghai Machinery Factory created “603 non-toxic carburizing agent”, but the carbon concentration on the surface of the carburizing parts used at that time generally can only reach the range of 0.6-0.7%, and can not be stabilized at 0.8-0.9%. To this end, I have different specifications of the 603 carburizing and carburizing salt bath and the use of technology made a systematic experimental study, more than two years after more than 100 tests, the first of three issues to be resolved : (1) the quality of the carburizing agent itself; (2) the effect of the neutral salt composition and mass of the carburizing salt tank on the result of carburizing; (3) the effect of the process specification of the carburizing process on the quality of the carburized layer .
