本文专门研究并确立了40CrNiMoA火焰筒固定销的离子轰击氮碳共渗生产新工艺。对处理结果进行的微观组织和宏观机械性能测试分析的数据表明,新工艺不仅在本质上优于气体渗氮处理,而且可提高工效8～10倍,大量地节约渗剂的用量,省电和无环境污染,经济效益显著。工件已通过实机飞行考验,获得完全可以取代原工艺的验证。 This article specializes in and establishes the 40CrNiMoA flame tube fixing pin ion bombardment nitrocarburizing production of new technology. The results of the microstructure and macro mechanical properties of the test analysis of the data shows that the new process is not only inherently better than the gas nitriding, but also to improve work efficiency 8 to 10 times, a substantial saving in the amount of penetration, power and No environmental pollution, significant economic benefits. Workpiece has passed the real machine flight test, access to completely replace the original process of verification.
