Quenching

Metal gear quenching is a heat treatment process widely used in industries like automotive, aerospace, heavy machinery, and industrial tooling to enhance the hardness and durability of gear components.

After gears are heated to high temperatures, they’re rapidly cooled—typically using oil, water, or polymer solutions—to lock in a martensitic microstructure, boosting wear resistance and strength.

Companies specializing in gear manufacturing, such as Gleason, AGMA-certified heat treaters, and major OEMs like Caterpillar, Ford, and GE Aviation, routinely perform gear quenching as part of their precision metallurgy workflows.
