Butterflies are microscopic damage features forming at subsurface material imperfections induced during rolling contact fatigue (RCF) in rolling element bearings. Butterflies can lead to degradation of the load bearing capacity of the material by their associated cracks causing premature spalling failures. Recently, butterfly formation has been cited to be related to a premature failure mode in wind...
This study has investigated the relationship between applied interfacial electrical potentials and friction and abrasion for steel/steel contacts in alkaline aqueous-based solutions. The potential at a steel-aqueous lubricated surface is important since it determines a number of important surface properties which influence the overall friction and resistance to abrasion. The experimental approach...
