TiNbCN carbonitride coatings were synthesised by cathodic arc evaporation at different C/N ratios (0.4 and 1.6, respectively) and a constant metal + Si ratio of 0.6, corresponding to a stoichiometric ratio for the coating of 1.6 and an over-stoichiometric ratio of 0.4. According to corrosion studies, both EIS diagrams and potentiodynamic curves indicated an evident difference between the investigated specimens in the fallowing order: TiAlV < TiNbCN-1 < TiNbCN-2, demonstrating the advantages of higher carbon content in TiNb-based nitride matrix. The investigation of the crystalline structure and surface morphology of the synthesised TiNbCN coatings was conducted both prior to and following corrosion, with a specific focus on the influence of the C/N ratio. Additionally, the surface morphology of TiNbCN coatings bombarded with high-energy and high-flux protons was examined. The structural investigations were conducted through the use of X-ray powder diffraction spectroscopy, while the surface morphology analysis was undertaken through the utilisation of scanning electron microscopy. It was determined that after corrosion, the lattice parameters of the TiNbCN coating increased by up to 0.4 %. Surface morphology analysis revealed no degradation of the surface and localized dislocations after corrosion. After bombardment with 2.0 MeV energy protons, a complete amorphization of nano-sized crystals and the formation of pin holes structures were observed in the surface morphology.
