Abstract
Recent attempts at improvements in V-22 gear life have focused on coatings over existing gear materials (for ex. DLC on Pyrowear 0053, or others), unfortunately for various reasons (interface failure, high contact stress, thermal expansion mismatch, etc.) these materials have never made an impact on the V-22 program or made it into Textron-Bell Helicopter's materials insertion programs. Currently, V-22 gears are made of low-carbon, low-alloyed steel that are manufactured, machined and then carburized (case hardened) at the gear surface to achieve a tempered martensitic case structure with the appropriate surface hardness, while maintaining the internal hardness, strength and toughness required for the gear performance. Recent advances in metal matrix composite fabrication now allow for the creation of functionally graded nano-composites with similar properties and performance. The increae in performance will provide increased powder density, reduced life cycle cost, operate at higher temperatures, decrease V-22 vehicle weight by reducing gear weight and the oil reserve required. The Advanced Powder Solution's team of experts in this area- will provide a significant effort in finding suitable replacements to provide the desired increase in power density.
