HEAT-RESISTANT COVER Russian patent published in 2016 - IPC C03C8/14 

FIELD: engines and pumps.

SUBSTANCE: invention relates to materials which protect parts of gas turbine engines that made out of heat-resistant steels and nickel alloys against oxidation under action of high-temperature gas corrosion during operation. High-heat resistant cover, mas%: Al₂O₃ - 13.0-18.0, MgO - 1.0-2.5, CaO - 3.0-8.0, BaO - 5.0-9.0, TiO₂ - 1.5-4.8, B₂O₃ - 3.5-7.6, Cr₂O₃ - 2.5-6.0, BaSi₂O₅ - 5.0-10.0, BaAl₂Si₂O₈ - 2.0-6.5, mineral complex compound based on SiO₂ - 2.5-6.0, SiO₂ - the rest.

EFFECT: higher heat resistance, thermal fastness, wetting ability of the surface of samples and strength of adhesion of coating with substrate.
