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 …

This paper proposes the concept of how machinery condition monitoring can be taken to the
next level, through micro-sensing of tribological phenomena occurring between contacting …

Presence of white etching cracks has been widely associated with early failures of rolling
bearings in a number of applications, with wind turbine gearbox bearings being the most …

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

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

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 a dominant mode of premature failure
within wind turbine gearbox bearings. Though WECs have been reported in the field for over …

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 …
