在伟大袖领毛主席革命路线指引下,我们学习了玉门石油管理局机械厂和兰州石油机械研究所等单位的先进经验,从一九七五年十月开始,应用硼酐为渗硼剂,开展气体碳氮硼三元共渗的新工艺探索试验,经过一个多月三十多炉次的试验,初步摸索出三种操作比较简便、费用比较低廉的共渗新工艺。试验过程中,大冶钢厂中心试验室和武汉大学的同志们给了我们很大的帮助。 Under the guidance of Chairman Mao’s revolutionary line, we studied the advanced experience of Yumen Petroleum Administration Machinery Factory and Lanzhou Petroleum Machinery Research Institute. From the beginning of October, 1975, the application of boric anhydride as a boronizing agent , To carry out the gas carbonitriding ternary exploration of new technology trials, after more than 30 months of more than a month test, initially explored three simple, relatively low cost of new technology common osmosis. During the experiment, Daye Steel Center Laboratory and Wuhan University comrades gave us a great help.
