Abstract:
A gear and a method of making a forged powder metal gear having a plurality of teeth and a variable case depth profile forged in the plurality of teeth. Each tooth of the plurality of teeth has a first surface and a tooth root. A variable case depth profile is formed in each tooth of the plurality of teeth, whereby the variable case depth profile exhibits greater tooth wear resistance on the first surface and greater impact resistance in the tooth root.
