Cold Spray Coatings Qualification for Repair of Aerospace Parts

Many aerospace parts on Boeing aircrafts cannot currently be easily repaired when damaged during operation due to the lack of existing economical-practical repair
technologies. For example, damaged aluminum coatings or chromium plating require that the coating/plating be completely removed and then reapplied, an extremely costly and time consuming process. Similarly, aluminum and titanium parts damaged during regular operation or even initial machining must be disposed of if the damage causes a thickness reduction below the minimum engineering requirements as there is no current process to repair those parts. The Cold Spray technologies commercialized by the manufacturing sponsor (Centerline (Windsor) Limited) produce metallic layers/coatings by accelerating metal powders onto the part to be repaired/coated using high velocity inert gas at supersonic speeds without damaging the parts to be coated.
