Pretreatment of High Temperature Ceramic Composites
Coated components, along with methods of their formation, are provided. The coated component may include a ceramic substrate having a Si-treated layer surrounding a ceramic core and an environmental barrier coating on the Si-treated layer of the ceramic substrate. The ceramic core may include silicon carbide, and the Si-treated layer may be pretreated to tailor its surface's properties for inhibiting or delaying the formation of carbon oxides to upon exposure of the Si-treated layer to oxygen.
