The actual service life of wind turbine gearboxes is often well below the desired 20 years.
One of the prevalent failure modes in gearbox bearing raceways is white structure flaking …

Subsurface crack networks surrounded by microstructural alterations, named as “White
Etching Cracks”(WEC), lead to wind turbine gearbox bearing (WTGB) premature failures …

Severe plastic deformation leads to cementite decomposition in pearlitic and martensitic
alloys, resulting in high-strength nanocrystalline ferrite. This effect can be employed to …

The formation of white etching cracks (WECs) in steel rolling element bearings can lead to
the premature rolling contact fatigue (RCF) failure mode called white structure flaking …

White etching cracks (WECs) have been identified as the dominant mechanism of premature
failure for bearings within wind turbine gearboxes. Though WECs have been observed in …

White etching cracks (WECs) and the associated white etching areas (WEAs) are
responsible for failure of widely spread engineering applications such as bearings and …

White etching crack (WEC) failure is distinct to classical fatigue and driven by the
composition of lubricants under special loading conditions; for example, slippage and …

Substantial microstructural changes, such as Dark Etching Region (DER), White Etching
Bands (WEBs) and White Etching Cracks (WECs), can occur in typical bearing steels such …

White etching cracks (WECs) have been studied over the last decades as a common cause
for premature failure of roller bearings in various applications. As a consequence of the non …

The high nitrogen bearing steel X30CrMoN15-1, marketed under commercial names such
as Cronidur30, VC444, NitroMax and N360, is well-known for its outstanding rolling contact …
