Resumen
Net shape manufacturing advantages and its cost effectiveness is well known for sintered structural
parts for many automotive applications. Combined with cost effective material solutions, plus smart
secondary processes, and finally leading to higher product performance, PM technology can add even
more value to customer processes and end user applications. This paper describes the conversion
study of a manual transmission component from wrought to pm steel, while presenting the results of
comparing the wear performance when subjected to moderate forces and high sliding velocities.
The authors analyzed the behavior of PM based Cr plus nitriding (gas or plasma) specimens in
comparison with a wrought steel plus carburizing. The component lifetime and reliability was evaluated
according to the IRG-diagram. The final conclusion is that the PM material has better wear
performance than the current wrought steel component.
