Özet

In this study, the effects of surface treatments on fatigue life of AISI 316L stainless steel were investigated. For this aim, the influences of the surface treatments, which are plasma nitriding, Ti-DLC thin film deposition, and duplex surface treatment (nitriding+Ti-DLC deposition) on fatigue life were determined by means of XRD, SEM, fatigue and microhardness tester. It was observed that applied surface treatments increased the fatigue strength of the 316L, in comparison with the untreated ones. Whilst the best fatigue strength was attained after duplex treatment, the fatigue life increased with increasing of the surface hardness.
