Документ Anti-corrosion ceramic coatings on the surface of Nd-Fe-B repelling magnets(National Science Center "Kharkov Institute of Physics and Technology", 2019) Taran, A. V.; Garkusha, I. E.; Taran, V. S.; Timoshenko, O. I.; Misiruk, I. O.; Skoblo, T. S.; Romaniuk, S. P.; Starikov, V. V.; Baturin, A. A.; Nikolaychuk, G. P.; Pyvovar, N. V.; Gnidenko, Yu. P.The results of vacuum-arc deposition of thin ZrO₂coatings to protect the surface of Nd-Fe-B permanent magnets used as repelling devices in orthodontics are presented. The structure, phase composition and mechanical properties of zirconium dioxide films have been investigated by means of SEM, XRD, EDX, XRF and nanoindentation method. It was revealed the formation of polycrystalline ZrO₂ films of monoclinic modification with average grain size 25 nm. The influence of the ZrO₂ coating in terms of its barrier properties for corrosion in quasi-physiological 0.9 NaCl solution has been studied. Electrochemical measurements indicated good barrier properties of the coating on specimens in the physiological solution environment.Документ Nanostructured ZrO₂ ceramic PVD coatings on Nd-Fe-B permanent magnets(Collegium Basilea, 2019) Taran, Anton; Garkusha, Igor; Taran, Valerij; Timoshenko, Alexander; Misiruk, Ivan; Starikov, Vadym; Baturin, Alexey; Skoblo, Tamara; Romaniuk, Svetlana; Mamalis, Athanasios G.The results of vacuum-arc deposition (PVD) of thin ZrO2 coatings to protect the surface of Nd-Fe-B permanent magnets used as repelling devices in orthodontics are presented. Magnetic devices are offered as an optimum and biologically safe forcegenerating system for orthodontic tooth movement. The structure, phase composition and mechanical properties of zirconium oxide films have been investigated by means of SEM, XRD, EDX, XRF and nanoindentation methods. The coatings are formed of polycrystalline ZrO2 films of monoclinic modification with average grain size 25 nm. The influence of the ZrO2 coating in terms of its barrier properties for corrosion in quasiphysiological 0.9% NaCl solution has been studied. Electrochemical measurements indicated good barrier properties of the coating on specimens in the physiological solution environment.
