Özet

In this study, the tribocorrosion behavior of untreated, plasma nitrided (450 °C–4 h), Ti-DLC coated and duplex treated (Ti-DLC coating after nitriding) AISI 316L stainless-steel were investigated. The plasma nitriding process was carried out in a gas mixture of 80 % H2 and 20 % N2 at 450 °C for 4 h. A titanium (Ti) interlayer was coated on the substrate for Ti-DLC coating. Then, a diamond-like carbon (DLC) film was grown on the Ti interlayer. As a result of the study, it was determined that the damage caused by the wear mechanism was much more than the corrosive effects. In general, thanks to the layers formed on the surface, the wear and tribocorrosion performance of the treated samples increased compared to the untreated sample. It was observed that the best tribocorrosion resistance among the treated surfaces was obtained in the duplex surface-treated sample.
