2015 PowderMet San Diego - Wrought steel gears and surface densified powder metallurgy gears – a comparison
Near net shape powder metallurgy components are used in a wide range of medium to heavy duty applications in automotive engines and transmissions due to their cost effectiveness as well as weight and energy savings. Powder metallurgy, nevertheless, is yet to penetrate the market for gears in automotive powertrains, despite past successes in other automotive applications. At first sight it may seem that traditional machining of transmission gears is a complex and expensive process. However, the reality today is that the design and manufacturing of gears is still an OEM core competence and the PM industry has been unable to convince automotive OEMs that it can produce parts that match the performance and dimensional accuracy of machined gears.
