    The distilled-water cavitation erosion resistance of Ti-6Al-4V alloy with vacuum-arc TiN and CrN coatings is investigated. The results show that the coatings having high mechanical properties are capable to reduce ...
  • Ovcharenko, V.D.; Kuprin, A.S.; Tolmachova, G.N.; Gilewicz, A.; Lupicka, O.; Rochowicz, J.; Warcholinski, B. (Вопросы атомной науки и техники, 2014)
    The application of protective coatings on metal materials is the effective way to improve their durability. Chromium nitride coatings are applied mainly on tools due to good resistivity to oxidation compared to other metal ...
  • Kuprin, A.S.; Kolodiy, I.V.; Ovcharenko, V.D.; Tolmachova, G.N.; Gilewicz, A.; Lupicka, O.; Warcholinski, B. (Вопросы атомной науки и техники, 2016)
    Due to good resistance to oxidation and wear chromium nitride coatings are widely used in industry. The works aimed at further improving, for example by carbon doping, the properties of the coatings. The goal of this study ...
