Wear and Rolling Contact Fatigue Analysis of AISI 52100 Bearing Steel in Presence of Additivated Lubricants

چکیده
Tribological properties of lithium potassium titanate (PT), molybdenum disulphide, and tungsten disulphide-dispersed mineral oil (MO) were investigated. The sample containing 2 wt.% WS2 exhibited the lowest coefficient friction. However, wear scar diameters additivated samples very narrow. Extreme pressure enhanced with addition additives. rolling contact fatigue results better life balls in MoS2 PT-dispersed MO. Surface characterization indicated more pitting on MO WS2-dispersed as compared to PT, indicating a stable film case which was confirmed by presence additives ball surfaces Raman spectrograph. extended tests proved that PT-added provided highest cycles tested balls, followed WS2-added oil; thus, PT plausible alternative WS2.

Hydrogen diffusion during rolling contact fatigue (RCF) is considered a potential root cause or accelerator of white etching cracks (WECs) in wind turbine gearbox bearing steels. Hydrogen entry into the bearing steel during operation is thought to occur either through the contact surface itself or through cracks that breach the contact surface, in both cases by the decomposition of lubricant th...
