Abstract
An article comprises a first outer layer; a second intermediate layer; and a substrate; wherein the second intermediate layer contacts the first outer layer at a first interface and the substrate at a second interface. The first outer layer comprises Al2O3—TiO2 and the second intermediate layer comprises a functionally graded material. The functionally graded material comprises a composition proximate the first interface being substantially free of Al2O3—TiO2 and at the second interface having Al2O3—TiO2 in amounts substantially equal to the first outer layer.
