Abstract
A method of manufacturing a part is provided. The method includes heating a gear in the presence of carbon to carburize a material of the gear to create a carburized gear, the gear having a plurality of gear teeth and which comprises a selected material. Next, the carburized gear is high pressure gas quenched to drive the carbon into the material of the gear to create a quenched gear. Next, the quenched gear is at least one of cavitation peened and laser peened to create a peened gear. Finally, superfinishing is performed on surfaces of the peened gear.
