Abstract
In the design of solid-lubricated gears, knowledge of the wear behavior is essential for service life calculations. The detailed wear analysis of a MoS2:Ti TiN solid lubricant system on gear analogy test specimens shows that continuous wear of the MoS2 solid lubricant takes place on the contact surface and a specific local wear characteristic occurs in the areas with initial roughness peaks. The question arises whether the specific wear characteristic can be determined with a wear calculation. By taking into account the real topography of the test shaft and experimentally determined wear coefficients, it was shown that a qualitative relationship exists between the real wear and the calculated total frictional energy on a local level. However, the wear calculation shows that further research is needed in the future to predict locally severe wear.
