Summary: ABSTRACT: Hydrogenated amorphous carbon (a-C:H) top layer was deposited onto 316L medical grade stainless steel by reactive magnetron sputtering with two types of interlayers, based on Cr and Ti. The goal was to evaluate the effect of the adhesion-promoting layers on the overall coating/substrate system. After the immersion test in acidic artificial saliva, no surface signs of corrosion were detected. However, the Cr-based interlayer enhanced the metallic ions release, whereas the Ti-based one seems to improve the corrosion resistance. Electrochemical Impedance Spectroscopy was also used to evaluate galvanic corrosion evolution at the adhesion interfaces.
