Abstract

A method of repairing an erosion coating (90) coupled to a substrate (82), wherein the coating (90) comprises an anodization layer (84) on the substrate (82), a bond primer layer (86) on the anodization layer (84), a corrosion-resistant primer (88) on the bond primer (86), and an erosion coating (90) on the corrosion-resistant primer (88) the method comprising abrading an erosion coating (90); abrading a corrosion-resistant primer (88); creating an abraded surface (104) comprising a bond primer (86) over an anodization layer (84) coupled to the substrate (82), chemically etching the anodization layer (84); abrading the bond primer (86); applying an anodization layer (84) to the substrate (82); applying a bond primer layer (86) over the anodization layer (84); applying a corrosion-resistant layer (88) over the bond primer layer (86); and applying an erosion coating layer (90) over the corrosion-resistant layer (88).
