Type: article

Abstract: The effect of hydrogen on the rolling contact fatigue life of steel was investigated using a four-ball rolling tester under a controlled atmosphere of hydrogen, deuterium and air. The isotope effect of deuterium on the fatigue life was observed, and thus the kinetic processes, such as the dissociation of deuterium molecule and the diffusion of deuterium atoms affect the fatigue life. Time-of-flight secondary ion mass spectrometry (TOF-SIMS) revealed that deuterium was absorbed and diffused into the steel during lubrication tests, and dissolved deuterium was concentrated underneath the friction track and around microcracks. The role of hydrogen in subsurface initiated fracture was considered based on the deuterium behavior observed by TOF-SIMS.
