Abstract: A method of manufacturing a part with a CMAS-resistant thermal barrier coating (TBC) includes providing a part body having a surface and providing a source of coating material. The coating material includes a thermal protection material and a CMAS-reactive material. The method also includes delivering the coating material from the source toward the surface of the part body to form the CMAS-resistant TBC on the surface. The CMAS-resistant TBC includes both the thermal protection material and the CMAS-reactive material. The CMAS-reactive material is included as a substantially uniform distribution within the thermal protection material.

Abstract: A method of preparing a coated article is disclosed. The method includes depositing a coating composition on a surface of a substrate to form a calcia-magnesia-alumina-silicate (CMAS)-resistant thermal barrier coating (TBC) thereon and give the coated article. The coating composition comprises from about 3 to about 50 wt. % of one or more rare-earth oxides, from about 45 to about 96.5 wt. % zirconia, and from about 0.5 to about 4 wt. % alumina, each based on the total weight of the coating composition. As deposited, the alumina is distributed substantially homogeneously throughout the CMAS-resistant TBC. A coated part prepared with the method is also disclosed.

Abstract: A method of manufacturing a part with a CMAS-resistant thermal coating includes providing a part body having a surface and forming a thermal barrier coating (TBC) layer on the surface. The method also includes providing a precursor of a CMAS-reactive material and depositing the CMAS-reactive material on the TBC layer using the precursor.
