Deep Cryogenic Thermal Processing to Improve Fatigue, Corrosion and Dimensional Stability of Pyrowear 675 Gearbox Bearings Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-022 Topic Title: Deep Cryogenic Thermal Processing to Improve Fatigue, Corrosion and Dimensional Stability of Pyrowear 675 Gearbox Bearings Proposal No.: N121-022-0754 Firm: Redstone Aerospace Corp. P.O. Box 1504 Longmont, Colorado 80502-1504 Contact: Jack Cahn Phone: (303) 772-9472 Abstract: Redstone Aerospace proposes the use of deep cryogenic processing to reduce corrosion effect and non-metallic inclusions in fatigue crack formation, to increase fracture toughness and to impart wear resistant characteristics in forged Pyrowear 675 rotorcraft gears. Benefits: The use of this process will lower the total cost of ownership and significantly increase the life of gears in high heat and abrasive wear environments that frequently lead to discrete part failure. Commercialization applications include military aircraft bearings and gearbox items in jet fighters and rotorcraft as well as naval ship turbine and propeller shaft assemblies, industrial use in power generation, turbines, compressors and commercial opportunities in automobiles, trains and aircraft.
