    Abstract: Embodiments of the present disclosure generally relate to protective coatings on an aerospace component and methods for depositing the protective coatings. The protective coating can be anti-coking coatings to reduce or suppress coke formation when the aerospace component is heated in the presence of a fuel. In one or more embodiments, a method for depositing a protective coating on an aerospace component includes depositing an optional barrier layer on a surface of the aerospace component and depositing a catalytic oxidation layer on the barrier layer and/or directly on the aerospace component. The barrier layer can be or include aluminum oxide, magnesium-doped aluminum oxide, dopants thereof, or any combination thereof. The catalytic oxidation layer can be or include cerium oxide or one or more oxygen storage materials.
