The Effect of Poly(alkyl methacrylate) Film-Formers on Pitting Performance of Driveline Fluids

Driven by diminishing fossil fuel resources, global warming and subsequently rigid legislation on CO2 emission, fuel economy is a major challenge for the automotive industry. Each element of the powertrain has been optimized or newly designed to increase efficiency. In this optimization process the...
