White etching crack (WEC) investigation by serial sectioning, focused ion beam and 3-D crack modelling

White structure flaking (WSF) as a premature wear failure mode in steel rolling element bearings is caused by white etching cracks (WECs) that form in the 1 mm zone beneath the contact surface. Hydrogen diffusion into raceways and transient operating conditions have been suggested as drivers of WSF....
