Abstract: The Cr 3 C 2 -NiCr/DLC duplex coating was successfully prepared on 316 L stainless steel through a combined method of high-velocity oxygen-fuel (HVOF) spraying and physical vapor deposition (PVD). The tribo-corrosion features of Cr 3 C 2 -NiCr coating, DLC film, and Cr 3 C 2 -NiCr/DLC duplex coatings in a 3.5 wt% NaCl solution were contrastively investigated. Tribo-corrosion tests were conducted under OCP (Open Circuit Potential) conditions, polarization conditions, and cathodic protection conditions, respectively. It was found that the tribo-corrosion resistance of the Cr 3 C 2 -NiCr/DLC duplex coatings was mainly associated with the synergistic effect of the top DLC film and the Cr 3 C 2 -NiCr intermediate layer. The Cr 3 C 2 -NiCr intermediate layer can provides robust support for the top DLC film, while the DLC film effectively seals the Cr 3 C 2 -NiCr intermediate layer, collectively enhancing the tribo-corrosion resistance of that duplex coatings. Notably, this duplex coating exhibits superior tribo-corrosion resistance, with a wear rate of 4.89 × 10−7 mm3/N·m. However, the Cr 3 C 2 -NiCr coating demonstrates the worst resistance to tribo-corrosion, with a wear rate of 1.83 × 10−5 mm3/N·m. During the tribo-corrosion process, the material loss of the Cr 3 C 2 -NiCr coatings is mainly caused by the interaction between corrosion and wear, whereas the material loss of the DLC film and the Cr 3 C 2 -NiCr/DLC coatings is mainly attributed to mechanical wear. In summary, the excellent property of the Cr 3 C 2 -NiCr/DLC duplex coatings were proved. [Display omitted] • HVOF/PVD duplex design significantly improved the tribo-corrosion resistance of DLC films. • Synergistic mechanisms between HVOF coating and PVD film were clarified from the aspects of anti-corrosion and anti-wear. • Interaction mechanisms between corrosion and wear of duplex coatings were quantitatively studied.
