Abstract
A method of improving the quality of metal matrix fiber reinforced monotape and thin foil overlays made by the arc spray process by tailoring the surface finish of mandrels used in the process to the overlay being formed and making the mandrels of materials with high thermal conductivity so that the spray applied overlays hold and adhere to the mandrel during the spraying process and are easy to remove from the mandrel without damaging the overlay after the spray has solidified.
