前言今年年初机械制造与工艺科学研究院与沈阳风动工具厂对国产气体渗碳剂进行了比较系统的研究,前一阶段的试验结果已在本刊第一期发表,现在把第二阶段试验成果继续发表供大家参考。渗碳剂选择补充试验前一阶段渗碳剂选择试验中我们做了厂用煤油、苯60%+酒精40%、合成煤油、合成煤油+正己烷及苯等五种渗炭剂试验,结果以苯+酒精及合成煤油+正己 Preface Earlier this year Machinery Manufacturing and Process Science Research Institute and Shenyang Fengdonggongju on the domestic gas carburizing agent conducted a more systematic study of the results of the previous phase has been published in the first issue of this publication now the second phase of the test The results continue to be published for your reference. Carbide selection supplementary test before the first stage of the carburizing agent selection test we made the factory with kerosene, benzene 60% + 40% alcohol, synthetic kerosene, synthetic kerosene + n-hexane and benzene five charring agent test results as Benzene + alcohol and synthetic kerosene + n-hexyl
