A technology has been developed for dispersed alloying of glass matrices to create superplastic coatings that allow isothermal deformation of alloys in the absence of special equipment. The developed protective glassy and glass-ceramic technological coatings have a strong internal structure and high film-forming ability; they withstand significant shock and tensile loads at high degrees of deformation (above 40%).

Silicate films obtained by the sol-gel method, doped with 1, 10, and 20% platinum, have been studied by X-ray electron spectroscopy and atomic force microscopy. The changes in the structure of the silicate film as a result of doping with platinum, as well as the effect of the concentration of platinum, temperature and heat treatment atmosphere on the composition and morphology of the surface of the doped films have been determined. Tab. 2, ill. 5, bibliography: 9 titles.
Thermal reinforcing coatings based on ceramic-forming polymers and modifying refractory oxygen-free nanosized particles have been investigated. It has been established that the use of heat-reinforcing coatings provides an increase in the operating temperatures of fibrous heat-insulating materials by 300 - 500 ° C, an increase in thermal and mechanical characteristics by a factor of 2-3. A new glass-ceramic composite multifunctional material with a thermo-reinforcing coating has been created, which can be used in heat-insulating, heat-shielding and sound-absorbing structures in aerospace engineering and power engineering. Il. 6, bibliography: 3 titles.
Glass-crystalline compositions based on leucite glass with an increased content of fluids and additions of hydroxyapatite or a mixture of hydroxyapatite with fluorite, intended for the manufacture of coatings on titanium implants, are considered. It has been established that masses containing no more than 30% hydroxyapatite in leucite glass are most suitable as glass-crystalline coatings for dentures. Masses with a high content of hydroxyapatite Ca 10 (PO 4 ) 6 (OH) 2 (more than 30%) can be recommended as coatings for intramandibular titanium implants. Tab. 2, ill. 3, bibliography: 8 titles.
