Abstract
According to a method for forming a coating system on a turbine engine component substrate that comprises a nickel-based superalloy substrate having at least one refractory metal included therein, a nickel-based layer is formed on the substrate, the nickel-based layer comprising at least one active material selected from the group consisting of elemental silicon and a silicon compound. The at least one active material is then diffused into the substrate. An yttrium-modified platinum aluminide bond coating, or a MCrAlX bond coating, may be then formed over the active material-modified nickel-based layer.
