摘要： The invention is directed to a material and method for obtaining a ceramic abradable system for high temperature applications. High purity partially stabilized zirconia and/or hafnia base material has higher sintering resistance compared to conventional 6-9 weight percent yttria stabilized zirconia systems. The benefits of these systems are higher service lifetime and low thermal conductivity to achieve high operating temperatures. System includes a superalloy substrate, oxidation resistant bond coat and a thick ceramic abradable top coat. Total coating thickness is about 0.5-5 mm. In some applications an intermediate layer of high purity partially stabilized zirconia or a partially stabilized YSZ/MCrAlY cermet is applied over the oxidation resistant bond coat. In other applications an abradable system is applied on top of a grid. Additional benefits should be reduced blade wear at high operating conditions.

The invention materials are high purity zirconia and/or hafnia partially or fully stabilized by one or any combinations of the following stabilizers: yttria, ytterbia, scandia, lanthanide oxide and actinide oxide. Limits for impurity oxide, oxides other than the intended ingredients, that lead to significantly improved sintering resistance were discovered. High purity coating structures suitable for high temperature cycling applications and for application onto a substrate were provided. In one structure, the coating comprises a ceramic matrix, porosity and micro cracks. In another structure, the coating comprises a ceramic matrix, porosity, macro cracks and micro cracks. In another structure, the coating comprises ceramic columns and gaps between the columns. In another structure, the coating comprises ceramic columns, gaps between the columns and nodules distributing randomly in the gaps and columns.

摘要： The invention is directed to a blended material and method for obtaining thermal barriers for high temperature cycling applications that have both high sintering resistance to achieve a high service lifetime and low thermal conductivity to achieve high operating temperatures. These materials are additionally suited for use in high temperature abradable (rub seal) coatings. The invention provides desired coating structures so that the changes in the coating microstructure over the in-service lifetime are either limited or beneficial.
