Abstract: Systems and methods may be used to produce coated components. Exemplary chamber components may include an aluminum, stainless steel, or nickel plate defining a plurality of apertures. The plate may include a hybrid coating, and the hybrid coating may include a first layer comprising a corrosion resistant coating. The first layer may extend conformally through each aperture of the plurality of apertures. The hybrid coating may also include a second layer comprising an erosion resistant coating extending across a plasma-facing surface of the semiconductor chamber component.
