“…Critical features of CrN coating include better wear resistance, corrosion resistance, heat resistance, and most importantly, ease of mold release [1][2][3][4][5][6][7][8][9]. When CrN is exposed to high temperatures, a dense and stable Cr 2 O 3 nanolayered film is formed on the surface as a protective layer [10].…”

Cr(N,O)/CrN based coatings were produced in the form of double-layered and four-layered structures, by the cathodic arc deposition process. These coatings were deposited onto tool steel substrates. The phase structure and morphology of coatings were observed by utilizing XRD, XPS and SEM. The corrosion behavior of these coatings was investigated using polarization tests, carried out in the solution of 1 M H 2 SO 4 solution. The SEM surface topography showed a smoother surface of the four-layered Cr(N,O)/CrN coating compared to that of CrN and Cr(N,O)/CrN double-layered coatings. The corrosion resistance of Cr(N,O)/CrN four-layered coatings with thinner thickness was better than that of CrN singlelayered and Cr(N,O)/CrN double-layered coatings, since pinholes in the coatings were effectively blocked by multi-layered structure.

“…Physical vapour deposition (PVD) of chromium nitride and its alloys with aluminium are emerging as a good alternative to other conventional surface treatments for tool protection [5][6][7][8]. PVD Cr-N has good hardness and toughness, which allows deposition of films as thick as 20 m without significant performance loss.…”

“…For example, in polymerforming operations, they exhibit a combination of outstanding wear resistance and chemical stability against polymer adhesion [2]. While the elastic properties of such coatings have been previously investigated [3][4][5], the relationship between chemical composition and fracture toughness has only been explored selectively [6,7].…”

We show here, based on VAlN, TiAlN and the related oxynitrides, that the (brittle) fracture and elastic properties may be consistently modelled from quantum-to continuum mechanics using micromechanical testing to link both scales. The measured elastic moduli match closely with those predicted by density functional theory calculations. Good agreement was also observed between the microcantilever bending experiments and cohesive-zone-finite element modelling. These scale-bridging data serve as a baseline for future improvements of the fracture toughness of these coating systems based on microstructure and coating architecture optimization. IMPACT STATEMENTWe link ab initio calculations with finite element modelling using micro-mechanical testing to consistently model the elastic and fracture behaviour of transition metal nitrides and oxynitrides.
