Abstract: Embodiments of the present disclosure generally relate to protective coatings on turbocharger components, such as turbine wheels and compressor wheels, and other rotary equipment components and methods for depositing the protective coatings on such components. In one or more embodiments, a coated turbocharger component is provided and includes a metallic substrate containing a nickel-based alloy or superalloy, a cobalt-based alloy or superalloy, a stainless steel, or a titanium-aluminum alloy and a protective coating disposed on the metallic substrate. The protective coating contains an aluminum oxide having a purity of greater than 99 atomic percent (at %). In some examples, the metallic substrate is a turbine wheel, a compressor wheel, an impeller, a fan blade, a disk, a heat shield, a pulley, or a shaft.

Abstract: Embodiments of the present disclosure generally relate to oxide layer compositions for turbine engine components and methods for depositing the oxide layer compositions. In one or more embodiments, a turbine engine component includes a superalloy substrate and a bond coat disposed over the superalloy substrate. The turbine engine component includes an oxide layer disposed over the bond coat, where the oxide layer includes aluminum oxide and a metal dopant. The turbine engine component includes a thermal barrier coating disposed over the oxide layer.
