Anew polyfunctional heat-resistant coating for protection from high-temperature gas corrosion (up to 900°C) swas synthesized based on glass in the system BaO–B2O3–SiO2. The synthesized heat-resistant polyfunctional coating has enhanced resistance to high-temperatures and high dielectric properties, thereby making it polyfunctional. The high level of the properties is afforded by a composition that is based on refractory glass and by the introduction of a coupling activator. [ABSTRACT FROM AUTHOR]

The bonding strength of an enamel reaction-cured coating on the heat-resistant nickel alloy VZh171 was investigated by means of sclerometry. The threshold load required for cracks to appear in a coating was determined. The values obtained are high for this type of material and correspond to the level typical for chromium and nickel coatings. The results of a microstructural analysis of the tested samples are also presented. The defects arising in each incremental load zone are described in detail. [ABSTRACT FROM AUTHOR]

The development of reaction-cured coatings is a promising direction in the field of the protection of metallic and nonmetallic structural materials (in operation) in aeronautical engineering. The main feature of these coatings is the possibility of forming (firing) them at close to operating temperatures and increasing their temperature stability at the same time. [ABSTRACT FROM AUTHOR]

Special heat-shielding materials cover the outer surfaces of space shuttles. These materials must also be protected from erosion, moisture, and so forth by thermal control coatings. A series of works was conducted at VIAM on the development and improvement of erosion-resistant thermal control coatings and their manufacture and usage technologies. [ABSTRACT FROM AUTHOR]

It is shown that zirconium-free frit should be used to obtain semi-fritted durable glass-crystal coatings, thereby decreasing the total fuel-energy consumption on the production of floor tiles by lowering the synthesis temperature of the frit by 80 - 100°C and decreasing the amount of frit in the raw material mix to 20 - 22.5%.

It is shown that the translucence of a substrate strongly influences light transmission by glass articles modified by sol-gel coatings. In contrast to glass, where light scattering is proportional to the refractive index, an inverse proportionality has been found in the films studied, which can be explained by the influence of porosity on the decrease of the refractive index of the coating.

IR spectroscopic and x-ray phase analysis established the structural specifics of glasses in the system Na2O-SiO2-TiO2-Na3AlF6, as well as the dependence on the type of crystallizing phases on the chemical composition of the glass matrix. The effect of the structure of titanium-bearing clusters on the leachability of glasses, the effect of the second coordination sphere on the coordination of the central cation (Ti4+), and the propensity of experimental glass coatings to opacification are registered.

Thermodynamic analysis of parallel-serial reaction in complex oxide systems is carried out. The use of the Karapet'yants method to supplement the refined Hooke-Jeeves method has made it possible to determine the optimum range of compositions studied and the most rational temperature interval for heat treatment of coatings. This makes it possible to substantially decrease subsequent experimental search and reduce it to a verification of the optimum interval that is thermodynamically identified. [ABSTRACT FROM AUTHOR]

The effect of the duration of treatment of the surface of soda-lime glass in potassium and lead nitrate melts at a temperature of 460°C on the chemical and mechanical strength is investigated. It is demonstrated that the formation of a crystalline lead-silicate coating in this treatment increases the alkali resistance threefold and the mechanical strength of glass twofold. Practical recommendations are issued. [ABSTRACT FROM AUTHOR]

It is found that the technological conditions for the formation of self-purifying coating depend on the sintering interval of the vitreous phase and its dispersion. The most porous coating with the maximum effect of self-purification (96 – 98%) was obtained on introducing 12 – 14 parts by weight of sodium silicate solution into the coating slip. The optimum coating structure provides for decomposition of food fats after multiple thermal cycling. [ABSTRACT FROM AUTHOR]
