The Effects of Hydrogen on Microstructural Change and Surface Originated Flaking in Rolling Contact Fatigue

The effects of hydrogen on microstructural change and surface originated flaking in rolling contact fatigue were investigated using JIS-SUJ2 bearing steel specimens charged with hydrogen. Under clean lubrication conditions, subsurface originated flaking occurred and the rolling contact fatigue life...
