The structure and composition of the coatings were studied by modern methods such as atomic force microscopy, scanning electron microscopy, photoelectron spectroscopy, X-ray analysis. As a result of work carried out comprehensive research to develop optimal conditions for preparation and modification of nanostructured surfaces by changing their surface states during irradiation by argon ions and medium-energy electron beam to control the processes of cell proliferation and differentiation of various origins. It was shown that the surface characteristics, roughness, microtopography significantly depend on the method of film deposition. The stoichiometric composition of the coatings also vary widely depending on the deposition conditions. In the case of coatings obtained by magnetron sputtering to form a film quality of the stoichiometric composition as compared with the analogues, deposited by electron beam deposition Product Description popup.authors Зикова Ганна Веніаминовна Сафонов Володимир Йосипович popup.nrat_date 2020-04-02 Close
