Документ Development of glass-ceramic high-strength material for personal armor protection elements(Національний університет "Львівська політехніка", 2017) Savvova, Oksana; Bragina, L. L.; Voronov, Gennadii; Sobol, Yuliya; Babich, Olena; Shadrina, Galina; Kuriakin, MykolaThe perspective of glass-ceramic high-strength materials used for personal armor elements has been established. The methodological approach has been developed and the choice of initial lithium aluminosilicate system for obtaining high-strength lightweight glassceramic materials has been substantiated. The glass formation area in the chosen system was studied, and model glasses were synthesized. Features of crystal structure formation during heat treatment of the developed model glasses were investigated. As a result, high-strength glass-ceramic materials have been developed. It has been determined that they possess high performance characteristics and can be used in manufacturing of modern composite armor.Документ Investigation of surface free energy of the glassceramic coatings on titanium for medical purposes(Lviv Polytechnic National University, 2015) Savvova, Oksana; Shadrina, Galina; Babich, Olena; Fesenko, ОleksiyBiocompatible calcium silicophosphate glassceramic coatings for titanium on the base of glasses in R₂О–RO–RO₂–R₂O₃–P2O₅–SiO₂ system have been obtained. The influence of crystallization ability and roughness of experimental coatings on their surface free energy has been established. The use of titanium implants with applied apatite-containing glass-ceramic coating will significantly increase biocompatibility of the prosthetic implant and will reduce the time of its union with the bone.
