We present the results of investigations of the influence of hydrogen-free carbonitriding in glow discharge on the physicochemical characteristics of the hardened layer of 40Kh steel depending on the content of propane and the pressure of gas atmosphere. We consider three versions of saturation: carbon + nitrogen, nitrogen + carbon, and simultaneous saturation with nitrogen and carbon. The analysis of the obtained results reveals the highest efficiency of hardening of the surface of 40Kh steel for the third version of saturation.

碳氮共渗40Kh钢的理化性能

我们介绍了辉光放电中无氢碳氮共渗对 40Kh 钢硬化层物理化学特性影响的研究结果，这取决于丙烷含量和气体气氛压力。我们考虑三种饱和度：碳+氮、氮+碳以及氮和碳同时饱和。对所得结果的分析表明，对于第三种饱和度，40Kh 钢表面的硬化效率最高。
