Abstract: MoS₂ is one of the widely known solid lubricants. However, it cannot be used in atmospheric environment due to its affinity for oxygen. The best way to reduce oxygen affinity is to add elements or compounds to the MoS₂ film. For this reason, in this study MoS₂ coatings were doped with Graphite-like carbon (GLC) using CFUBMS method. The MoS₂ film was doped by using different C₂H₂ ratios. The mechanical and electrochemical properties of the films for both undoped and doped coatings were examined. The results of the study have shown that undoped MoS₂ film has the worst mechanical and electrochemical properties. On the other hand, with the increasing flowrate of C₂H₂, an improvement was observed in the mechanical properties, thickness and electrochemical properties of the films. Moreover, at the highest C₂H₂ ratio used in this work, the highest adhesion value of 90 N was observed.
