本文结合Fe-N-C三元相图讨论了等离子体-阴极界面上发生的碳吸附和溅射过程对化合物层（CL）结构的影响。还研究了包括氧气在内的气体成分对CL发展的影响。本文根据离子氮碳共渗的机理，提出了一种制备近单相CL的工艺，并将其应用于普碳钢。
In this paper the processes occurring at the plasma–cathode interface (carbon absorption and sputtering) which are responsible for the structure of the compound layer (CL) are discussed in conjunction with the ternary Fe–N–C phase diagram. The influence of the gas composition, including oxygen, on the development of the CL is also investigated. Based on the mechanisms of plasma nitrocarburising described in this paper a technique to produce CLs with a structure close to epsilon monophase was developed and applied to plain carbon steels.
