A new experimental methodology to assess gear scuffing initiation
Tribology - Materials, Surfaces and Interfaces, 2022 This paper investigates the strong coupling between friction power losses and film thickness that prevent from clearly identifying the mechanism of scuffing through classical test procedures. As the film thickness appears of great influence on the phenomena, a new test method is presented, allowing scuffing initiation study with the film thickness as a
