HEAT-SHIELDING COATING PRODUCTION PROCESS Russian patent published in 1994 - IPC

Abstract RU 2021389 C1

FIELD: chemical industry. SUBSTANCE: heat-shielding layer is obtained by applying a heat-resistant sublayer based on nickel, cobalt or iron and a main layer of partially stabilized zirconium dioxide which contains additionally 5 to 40 volume per cent of inclusions consisting of glass particles. The starting point of its softening temperature is below the coating operating temperature. EFFECT: coatings thus obtained feature high destruction viscosity and low level of stresses on the boundary between the sublayer and the heat-shielding layer of the coating. 3 tbl
