An coated component is provided. The coated component includes a component substrate and bond coat layer comprising silicon deposited on the component substrate. A composite layer is deposited on the bond coat layer. The composite layer includes a rare earth disilicate and a second phase material. The composite layer has a thickness (T) from about 0.05 mm to about 2.25 mm, and a coefficient of thermal expansion that is different by a value of about 0 to about 2.25 from a coefficient of thermal expansion of the component substrate upon which the bond coat layer is deposited. Coated gas turbine engine components are also provided.
