Thermal barrier coating with reduced sintering and increased impact resistance, and process of making same

摘要

A composition is disclosed that includes an at least partially stabilized zirconia matrix with a pentavalent oxide first dopant and an oxide second dopant. A coated article is disclosed for use in a high temperature a gas turbine. The coated article can include an yttria-stabilized zirconia, a pentavalent oxide first dopant, and an oxide second dopant. The ratio of the pentavalent oxide second dopant to the oxide third dopant can be less than or equal to about 1. The composition can reduce sintering of the thermal barrier coating.
