Comparing acquisition and operation life cycle costs of powder metallurgy and conventional wrought steel gear manufacturing techniques

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift


The automotive industry has striven for fuel economy and resource efficiency through the deployment of powder metallurgy (PM) manufacturing processes for few decades. However, PM technology for transmission gears is currently only used at a small scale within the automotive industry. This is mainly due to: its shortcomings in material properties and performance gaps for final parts; lack of advancement in pressing technologies (dimensional limitation); lack of data availability (e.g. on materials, load capacity calculations; gear design experimental confirmation); premature failed attempts on PM gears; economics of scale and large initial capital investments. This article reviews the current state of the art of PM gear manufacturing technology highlighting an important gap in technical and financial data availability for PM gear economic analysis. Thus, this study seeks to give some empirical evidence of the economic aspects of PM gear manufacturing. Data availability is still the major challenge with respect to PM cost calculations thus further studies are needed to quantify both the economic and non-economic benefits e.g., sustainability, noise vibration harshness (NVH) of PM adoption.
