Документ Stimulation of calcium phosphate crystal formation by implant surfaces with electret properties(Collegium Basilea & AMSI, 2015) Starikov, V. V.; Starikova, S. L.; Mamalis, A. G.; Lavrynenko, S. N.Oxide coatings with electret properties are investigated. The possibility of stimulation of the formation of calcium phosphate sediments near the electroactive surface is discussed. The exposure of implants with such coatings to solutions imitating blood plasma showed their high efficiency of biointegration due to activation of an exchange processes in living tissues by a negative superficial charge. The revealed effect amplifies with the growth of the thickness of the anodic oxide film.Документ Properties of magnetron hydroxyapatite coatings deposited on oxidized substrates(Collegium Basilea & AMSI, 2016) Starikov, V. V.; Kostuchenko, A. V.; Starikova, S. L.; Mamalis, A. G.; Lavrynenko, S. N.Hydroxyapatite (HA) coating were formed on oxidized niobium surfaces by the highfrequency magnetron sputtering method using hydroxyapatite and tricalcium phosphate targets. The structure, substructure and mechanical properties of the Nb–Nb2O5–HA system were investigated by X-ray diffraction, atomic force microscopy and nanoindentation and the stress state was assessed. The synthesized hydroxyapatite film had the following characteristics: thermal expansion coefficient 10–5 K–1; modulus of elasticity 120 GPa; adhesive strength not less than 0.45 kg/mm2; density 2900 kg/m3. The stress magnitude in the metal oxide substrate was from 11 to 14 MPa after hydroxyapatite film deposition.Документ Diamond biocompatible coatings for medical implants(Collegium Basilea & AMSI, 2016) Starikov, V. V.; Starikova, S. L.; Mamalis, A. G.; Lavrynenko, S. N.New carbon (diamond-like) nanocomposite coatings deposited from a C60 ionic beam can be used as a wear-resistant protective coating for implants. It was found that these coatings enhance resistance to тelectrochemical corrosion processes due to a shift of the material’s electrode potential to a zone of positive values. They also promote a complex of reparative, adaptative and compensatory reorganization that accelerates the healing processes in the vicinity of the implant.
