Abstract
Official abstract text for this publication.
Coating systems and processes by which the coating systems can be deposited to be resistant to contaminants, and particularly resistant to infiltration and damage caused by CMAS. The coating systems include inner and outer ceramic layers, each having a microstructure characterized by splats and horizontal porosity. The inner ceramic layer consists essentially of zirconia stabilized by about 6 to about 9 weight percent yttria. The outer ceramic layer overlies and contacts the inner ceramic layer to define the outermost surface of the coating system. The outer ceramic layer consists essentially of zirconia stabilized by about 25 to about 75 weight percent yttria, has a thickness that is less than the thickness of the inner ceramic layer, and has a porosity level that is lower than that of the inner ceramic layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coating system on a surface region of a component, the coating system comprising: a bond coat; and inner and outer ceramic layers each having a microstructure characterized by splats and horizontal porosity, the inner ceramic layer overlying the bond coat, the inner ceramic layer consisting essentially of zirconia stabilized by about 6 to about 9 weight percent yttria, the inner ceramic layer having a thickness and a porosity level, the outer ceram…
