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.

Processes and tooling associated with coating application

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.

Fluoroelastomer erosion coating repair

An airfoil member () comprising has a substrate () along at least a portion of an airfoil () of the airfoil member. A sheath () has a channel () receiving a portion () of the substrate. A scrim () is between the substrate and the sheath. A spacer () is between the sheath and the substrate and has a plurality of spaced-apart portions () with gaps between the spaced-apart portions.

Fan blades and manufacture methods

A method for anodizing a bonded assembly may include attaching a first electrode to a first component of the bonded assembly, and forming a first oxide layer on the first component. The bonded assembly may comprise the first component and a second component bonded to the first component. The second component may be electrically isolated from the first component.

Anodization of bonded assembly

An airfoil member () comprising has a substrate () along at least a portion of an airfoil () of the airfoil member. A sheath () has a channel () receiving a portion () of the substrate. A plurality of separate spacers () are between the sheath and the substrate and have a plurality of gaps between the spacers.

A method of remanufacturing a liner panel for a gas turbine engine includes removing a bushing from a damaged component; and molding the bushing with a material charge. A liner panel for a gas turbine engine includes a forward fan exit case liner panel with a donor bushing from a damaged forward fan exit case liner panel. A liner panel for a gas turbine engine includes a forward fan exit case liner panel molded from a material charge that includes a multiple of layers. At least one of the multiple of layer includes a discontinuity.

A method of inspecting components between a pre-coated state and a post-coated state is provided. The method entails providing at least first and second datum points onto the component in the pre-coated state, where each of the at least first and second datum points have a substantially hemi-spherical shape and a center point. The center points of each of the at least first and second datum points are utilized for measurement of a selected portion on the component in the pre-coated state. Then, the component is coated. Next, the center points of each of the at least first and second datum points are utilized for measurement of the selected portion on the component in the post-coated state. The pre-coated state measurements and the post-coated state measurements are then correlated for inspection purposes.
