Abstract

The structure and corrosion performance of PVD Cr-N coatings were studied to understand the influence of the composition, thickness, and substrate surface roughness on the corrosion resistance of such coatings on steel substrate. Nitrogen gas flow rate, multilayered structure, and the steel surface finish prior to coating all significantly affected the microstructure of PVD Cr-N coatings, changing the corrosion resistance of such coated systems in 0.5N NaCl solution. Multilayered coating structures markedly improved the corrosion performance of steel. The steel substrate surface finish significantly affected the uniformity and coverage of PVD coatings.
