ABSTRACT:
A method for increasing the corrosion resistance of honeycomb core panel construction by using an ion implantation process. In one aspect of the invention, molybdenum ions are implanted to a predetermined depth into the front and back surfaces of a honeycomb-shaped core. The ions interact with the metal in the core wall to form an aluminum-molybdenum alloy which is impervious to corrosion. In another aspect of the invention, both front and back surfaces of the honeycomb-shaped core are bombarded with ions so that the ions are implanted throughout the entire core wall. The method may also be extended to include implanting ions into the outer skin layers to achieve enhanced corrosion resistance.
