Experimental method for hydrogen-induced rolling contact fatigue

    Research output: Contribution to journalArticlepeer-review

    Abstract

    The actual service life of component is often below the desired life. One of the prevalent failure modes in bearing raceways is hydrogen-induced rolling contact fatigue (RCF) with associated microstructural change called white etching constituent. Despite these failures having been observed for a long time in various industries, the detailed reasons and mechanisms for their formation are not fully understood. In this review, experimental methods for hydrogen-induced RCF are discussed, specifically hydrogen charging, hydrogen content measurement in steel and various types of RCF testers. The review also highlights the surface and subsurface observation technique. Beneficial surface treatment and enhanced lubrication with additives are shown as countermeasures to prevent diffusion of hydrogen into the metal.
