THERMAL BARRIER COATING WITH LOW THERMAL CONDUCTIVITY
PROBLEM TO BE SOLVED: To provide an article having superalloy substrates with thermal barrier coatings.SOLUTION: This invention relates to an article 10. The article 10 comprises a superalloy substrate 14 that is disposed with a bond coating 16 and a thermal barrier coating 20. The thermal barrier coating 20 is disposed on the bond coating 16 and comprises an inner ceramic layer 22 and an outer ceramic layer 24. The outer ceramic layer 24 comprises a material having a composition represented by formula I. (alkaline earth metal)x(rare earth metal)y(Zr, Hf, Ti)zOδ(I). In the formula I, x>0, y>0, z>0, δ>0 and [y/(x+y+z)]≥0.28. The composition of the formula I has the cubic fluorite structure.SELECTED DRAWING: Figure 1
【課題】遮熱コーティングを有する超合金基材を含む物品を提供する。【解決手段】物品１０に関する。物品１０は、ボンドコーティング１６および遮熱コーティング２０と共に配置される超合金基材１４を含む。遮熱コーティング２０は、ボンドコーティング１６に配置され、内側セラミック層２２と、外側セラミック層２４とを含む。外側セラミック層２４は、式Ｉの組成を有する材料を含む。（アルカリ土類金属）x（希土類金属）y（Ｚｒ、Ｈｆ、Ｔｉ）zＯδ（Ｉ）。式Ｉにおいて、ｘ＞０、ｙ＞０、ｚ＞０、δ＞０、および［ｙ／（ｘ＋ｙ＋ｚ）］≧０．２８である。式Ｉの組成は、立方晶蛍石構造を有する。【選択図】図１
