Formation of surface film and hydrogen permeation under rolling/sliding contact
Formation of surface film and hydrogen permeation under rolling/sliding contact
Bearing steels experience degradation in mechanical properties when atomic hydrogen diffuses into the material from the contact surface. In rolling contact fatigue tests, increasing hydrogen uptake can significantly reduce specimen fatigue life.
To address this issue, synthetic oils with different chemistries were investigated to evaluate their effectiveness and mechanisms in retarding or preventing hydrogen permeation. Thrust bearing tests were performed using three synthetic base oils. The influence of base oil chemistry on hydrogen generation and diffusion into bearing steel was assessed by correlating hydrogen concentrations in the specimens with observed changes in the wear track surface, subsurface microstructure, and oil condition.

Abstract
Bearing steels experience degradation in mechanical properties when atomic hydrogen diffuses into the material from the contact surface. In rolling contact fatigue tests, increasing hydrogen uptake can significantly reduce specimen fatigue life.
To address this issue, synthetic oils with different chemistries were investigated to evaluate their effectiveness and mechanisms in retarding or preventing hydrogen permeation. Thrust bearing tests were performed using three synthetic base oils. The influence of base oil chemistry on hydrogen generation and diffusion into bearing steel was assessed by correlating hydrogen concentrations in the specimens with observed changes in the wear track surface, subsurface microstructure, and oil condition.
