Abstract
A forged composite gear and a method of making a forged composite powder metal gear. The forged composite gear includes a plurality of teeth extending from a core, a first section having a first powder metal material, a second section having a second powder metal material and a variable boundary profile. The variable boundary profile is formed between the first section and the second section, whereby said variable boundary profile exhibits greater tooth wear resistance on the teeth and greater impact resistance in the core.
