ABSTRACT:
A process for increasing the corrosion resistance of honeycomb core panel construction by using an ion beam enhanced deposition. In one aspect of the invention, molybdenum ions are embedded a predetermined depth into the front and back surfaces of a honeycomb-shaped core. The ions interact with the core metal to form an aluminum-molybdenum alloy which is impervious to corrosion. A thin film coating of metal simultaneously is produced on the surface of the metal-ion embedded core metal. The process also may be used to embed ions into the outer skin layers to achieve enhanced corrosion resistance.
