..., which eventually leads to material removal. The alternating stress field in RCF is either pure rolling (e.g., rolling-element bearings) or rolling-sliding (gear tooth loading). The distinction between these two is comprised of the existence of gross sliding between mating parts, because microslip...

... spraying A MAJOR CAUSE of failure in components subjected to rolling or rolling/sliding contacts (e.g., rolling-contact bearings, gears, and cam/tappet arrangements) is contact fatigue. Rolling-contact fatigue (RCF) can be defined as the mechanism of crack propagation caused by the near-surface...
