Abstract
A CMAS resistant overlay coating including at least one CMAS resistant layer, wherein the overlay coating is i. disposed over a surface of a substrate including a material susceptible to CMAS corrosion, ii. includes a metal oxide matrix and iii. has at least partially a vertical columnar structure. Moreover, at least one non-oxidized metallic constituent selected from the group of aluminum, chromium and metallic constituents including aluminum and chromium is embedded in the metal oxide matrix. Furthermore, a substrate has a CMAS resistant overlay coating at issue on a surface of a material susceptible to CMAS corrosion. A CAE process is provided for forming such a CMAS resistant overlay coating on a surface of a material susceptible to CMAS corrosion.
