一、前言 遵照毛主席关于“人类总得不断地总结经验”,“有所发现、有所发明、有所创造、有所前进”的教导,我们学习了玉门石油管理局机械厂和其他兄弟单位的先进经验,于1975年开始在江汉石油管理局钻采设备研究所进行了以含氧硼化物力渗硼剂的气体碳氮硼共渗试验。在试验过程中,坚持以阶级斗争为纲,坚持开门办学、开门办科研,搞好工人、干部和技术人员的三结合和厂、校、所的三结合。经过近一年的工艺试验和现场试验表明,零件经共渗处理后的硬度、渗层深度、金相组织和耐磨性能与液体三元共渗相当,工艺操作简便。
I. Preface In accordance with Chairman Mao’s teachings on “mankind always has to sum up experiences”, “discoveries made, inventions made, advances made”, we have learned from Yumen Petroleum Administration Machinery Factory and other fraternal units Of the advanced experience, started in 1975 Jianghan Petroleum Administration Drilling Equipment Institute carried out with oxygen boride boronizing agent gas carbonitriding test. In the course of the experiment, we must adhere to the principle of class struggle as the key link, adhere to the principle of opening a door to running a school, open a door to conduct scientific research, and improve the combination of the three parties of workers, cadres and technical personnel with factories, schools and institutes. After nearly a year of process tests and field tests showed that the parts after the osmosis treatment of hardness, depth of penetration, microstructure and wear resistance and liquid ternary permeation equivalent process easy.
