Abstract: A drench system includes a rotating mount to rotate a workpiece, a showerhead to dispense a fluid onto the workpiece; and a tray to collect the fluid and recirculate the fluid to the shower. A method of repairing or remanufacturing a coating includes abrading a surface to at least partially remove a portion of a coating to leave an abraded surface; applying a sol-gel over the abraded surface; applying a corrosion resistant primer onto the sol-gel; and applying an erosion coating onto the corrosion resistant primer.

Abstract: Disclosed is a method of repairing a rear cone segment erosion coating including removing a portion of an existing fluoroelastomer coating from a rear cone segment to form a repair area; forming a cured replacement erosion coating corresponding to the repair area, wherein the cured replacement erosion coating has a layer of fluoroelastomer and a layer of fibrous reinforcement; preparing the repair area and the cured replacement erosion coating for adhesion; locating the prepared cured replacement erosion coating on the prepared repair area; and adhering the prepared cured replacement erosion coating to the prepared repair area. Also disclosed is a cured replacement erosion coating and a repaired inlet nose cone.
