METHOD OF THERMAL PROTECTION AND METAL ARTICLE WITH CERAMIC COAT (VERSIONS) Russian patent published in 2004 - IPC

FIELD: metallurgy; production of metal articles with ceramic coats, for example, blades of gas-turbine engine turbines. SUBSTANCE: proposed metal article has ceramic coat containing gadolinium and zirconium and ensuring thermal barrier. Material may have structure of fluorite or pyrochlore. Proposed method includes application of ceramic primer before application of ceramic coat. Primer contains zirconium oxide stabilized with yttrium oxide located between metal matrix and ceramic coat. Ceramic coat is applied by method selected from group consisting of thermal spraying, precipitation and vacuum deposition. EFFECT: possibility of working at very high temperatures. 25 cl, 13 dwg 2 tbl, 2 ex
