摘要

Austenitic stainless steel 316L (AISI 316L) is commonly employed in marine applications. However, this substrate is exposed to wear and corrosion conditions. To protect AISI 316L substrate from wear and corrosion attacks, it could be coated. In this study, diamond-like carbon (DLC) films were deposited on nitriding AISI 316L substrate. Then, the adhesion, hardness, wear and corrosion resistance of the DLC coated samples were studied. The coating was characterized by X-ray diffraction analysis (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy (RS) and field emission scanning electron microscopy (FESEM) and nano-indentation methods. Plasma nitriding treatment increased the adhesion of the DLC coating on the AISI 316L substrate. Electrochemical measurements and wear tests showed that deposition of the DLC coating improved corrosion and wear resistance of the AISI 316L substrate.
