“…A slightly decreased I D / I G ratio means an increase in sp 3 content, and this trend implies that the films become more diamond-like (i.e., less sp 2 content). In addition, many studies have shown that H α and CH contents are increased in high-energy plasma environments, thereby enhancing the formation of hydrogen bonds in the film structures to help form more stable sp 3 bonds, which again indicates that the advantages of plasma-assisted carburizing technology to prepare DLC films. − …”

Three different types of surface-modified layers of N, C, and N+C are successfully prepared on AerMet100 steel by plasma-assisted thermochemical treatment, and diamond-like carbon (DLC) films are formed on the top surfaces of the latter two. The results show that the DLC films produced by prenitriding and then carburizing (N+C) exhibit a smoother and finer morphology and higher sp 3 content than that without prenitriding (C). In addition, the wear resistance of the N+C specimen with a high hardness nitrided layer as the support for the outermost DLC films is superior to that of the C specimen. In view of the catalytic effect of the Fe 3 C phase on the growth of DLC films, the interfacial properties of Fe 3 C(001)/diamond(111) are investigated using first-principles calculations. On the basis of the most preferred Fe-terminated HCP site model, the effects of alloyed cementite (Fe 2 MC) on interfacial adhesion of Fe 2 MC(001)/diamond(111) are also investigated. Furthermore, the mechanisms of interfacial adhesion for two representative dopings (Zr weakened and V enhanced) are revealed in detail. These results are expected to provide a potential promising means for future experimental works on the preparation of high-performance DLC films on alloy steel surfaces by plasma carburizing.
