简介 A process for forming a coating on a substrate, such as a turbine engine component, is provided. The process comprises the steps of providing a rare earth oxide stabilized zirconia composition, blending the first rare earth oxide stabilized zirconia composition with at least one additional constituent selected from the group consisting of TiO2, Al2O3, a blend of Al2O3—TiO2, La2Zr2O7, and 20 wt % Yttria Stabilized Zirconia; and depositing the blended powder onto the substrate. Articles having the coating formed from the above process are also described.
