The power generation from wind farms is growing very fast all over the world, and wind
energy is now playing the most significant role to aid sustainable development since the last …

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

Despite of more than two decades of research in white etching areas (WEAs), this
phenomenon still persists in wind turbine gearbox bearings leading to a reduction of L 10 …

White etching areas (WEAs) are premature failure witnessed in wind turbine gearbox
bearings, due to which it fails within 10% of design life causing huge economic losses …

The premature failures in wind turbine gearbox bearings are primarily caused by the decay
of subsurface microstructure called white etching areas and white etching cracks. Severe …

White etching areas (WEAs) and white etching cracks (WECs) are the catastrophic
premature failure modes associated with wind turbine gearbox bearings. Several drivers …

Hydrogen precharged specimens were tested in a disc-on-disc tribometer to study the early
stages of crack formation that, with cycling, eventually generate WEC or WSF. Specimens …

Premature bearing failures commonly occur in applications that operate under extreme
boundary conditions. The lubrication engineers and tribologists are confronting a key …

This study investigates the effect of loading frequency and hydrogenation to instigate the
White Etching Areas (WEAs) formation under severe sliding condition of bearing steel …

The subsurface white etching microstructure (WEM) was an important reason to cause the
rolling contact fatigue (RCF) failure of wheel materials. The WEM formation mechanism in …
