Abstract
An article having a coating system configured to inhibit or prevent crystallization of a thermally grown oxide (TGO) layer at the operating temperature of the article. An article includes a substrate defining a surface and a coating layer that includes a dopant configured to inhibit crystallization of a thermally grown oxide layer comprising amorphous silicon dioxide at an interface of the coating layer at the operating temperature of the article. The dopant includes an oxide or a nitride. By inhibiting or preventing TGO crystallization, the described coating systems may increase a useable life of the component.
