  • DOUBLE-LAYERED ZIRCONIUM OXIDE LAYER HAVING A HIGH-PURITY CONTENT
    Publication number: 20170298519
    Abstract: By the use of highly pure zirconium oxide material for the outermost thermal barrier coating of a two-layer thermal barrier coating system, improved and durable layer systems for high-temperature temperature use is provided. A ceramic thermal barrier layer system, comprising: a substrate, a metallic adhesion-promoting layer on the substrate, an inner ceramic layer on the adhesion-promoting layer, and an outer ceramic layer on the inner ceramic layer, wherein the inner ceramic layer and the outer ceramic layer together represent the ceramic thermal barrier layer on the adhesion-promoting layer, wherein the outer ceramic layer is at least 20% purer, than the inner ceramic layer in terms of its chemical composition.
