Abstract

FIELD: chemistry.
SUBSTANCE: invention relates to the silicates technology, namely to glass coating compositions for articles made of ceramics and metals. The coating contains, wt %: SiO2 20.0-30.0; Al2O3 10.0-20.0; B2O3 4.0-6.0; ZrO2 31.0-34.5; CaO 2.0-6.0; Na2O 2.0-3.5; HfO2 13.0-15.0; CuO 1.0-2.0. Raw materials in the form of fine powders are mixed, the mixture is applied to the surface of ceramic or metal products in a stream of low-temperature plasma.
EFFECT: high heat resistance of the coating.

Компоненты для получения стекловидного покрытия (тонкодисперсные порошки кварца, глинозема, циркона, плавленой буры, мела, оксида гафния, оксида меди) смешивают в требуемых количествах. Смесь наносят на поверхность керамических или металлических изделий в струе низкотемпературной плазмы согласно методике [2].The components for obtaining a vitreous coating (fine powders of quartz, alumina, zircon, fused borax, chalk, hafnium oxide, copper oxide) are mixed in the required quantities. The mixture is applied to the surface of ceramic or metal products in a jet of low-temperature plasma according to the procedure [2].
