    Abstract: A method is provided for repairing a component of an item of rotational equipment, where the component includes a coating and a component body, and where the coating is on the component body and includes a defect. The method includes steps of: (a) removing a portion of the coating from the component body thereby forming a coating aperture, the removed portion of the coating including the defect, and the portion of the coating is removed such that the coating aperture has a coating aperture configuration which substantially matches a first patch configuration of a first coating patch; (b) preparing the component at the coating aperture to receive the first coating patch, (c) disposing the first coating patch within the coating aperture; and (d) attaching the first coating patch to the component body.

    Abstract: A method of repairing an erosion coating coupled to a substrate, wherein the coating comprises an anodization layer on the substrate, a bond primer layer on the anodization layer, a corrosion-resistant primer on the bond primer, and an erosion coating on the corrosion-resistant primer the method comprising abrading an erosion coating; abrading a corrosion-resistant primer; creating an abraded surface comprising a bond primer over an anodization layer coupled to the substrate, chemically etching the anodization layer; abrading the bond primer; applying an anodization layer to the substrate; applying a bond primer layer over the anodization layer; applying a corrosion-resistant layer over the bond primer layer; and applying an erosion coating layer over the corrosion-resistant layer.
