A FIB/TEM study of butterfly crack formation and white etching area (WEA) microstructural changes under rolling contact fatigue in 100Cr6 bearing steel
Significance of output:
This research was initiated through a high-level visit from Vestas in 2009. £105k funding was provided to investigate a key failure mode white etching flaking (WSF) occurring in wind turbine bearings (Ole Lund Jensen, OLJ@vestas.com). WSF is costing wind industry billions of pounds every year and the FIB/TEM analyses presented here have much improved the understanding on WSF. The work has attracted attentions from a wide range of academics and industries and led to two invited talks in 2012 and one in 2013 (HiperNano by KTN, European Base Oil & Lubricant Summit in Prague and VDI in Hamburg).
