Therefore, samples were plasma nitrided in a glow discharge environment and then, they were coated with diamond-like carbon (DLC) film. Electrochemical impedance spectroscopy, potentiodynamic polarization and tribocorrosion tests were performed in fourteen different parameters. Nitriding treatment increased the surface roughness compared to the base material. The negative effect of roughness on corrosion and tribocorrosion performance has disappeared with the ceramic film thickness increasing with temperature and time. Harder surfaces compared to the base material contributed to the wear resistance. Compound, diffusion layers and DLC film have a barrier effect, delaying the arrival of the corrosive liquid to the base material. © 2020 Elsevier LtdElsevier Ltd2021Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/13366https://doi.org/10.1016/j.triboint.2020.1068230301-679XenTribology Internationalinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/13366
