Annotation | This paper presents the results of investigation multilayer TiN / MoN coatings. Coatings were fabricated using Arc-PVD method. Period thickness of nanoscale layers in coatings was λ = 8, 25, 50 and 100 nm. The total thickness of coatings was up to 8.4 m. Samples were studied using SEM, TEM, EDS, RBS, XRD, SIMS and nanoindentation. The actual thickness of the layers has a few larger values than expected (in most cases per 25 %). The formation of two phases was found: stoichiometric TiN (fcc) and cubic γ-Mo2N (fcc). Maximum values of hardness and elasticity modulus were obtained for coating with λ = 8 nm: H = 47 GPa, E = 470 GPa. Plasticity index and its dependence on the thickness of layer period (λ) were calculated. The most plastic coating was the sample with H / E = 0.1. |
