This paper overviews studies in progress in the author’s group on tribology in hydrogen. The studies are on friction and wear of a range of materials in hydrogen, rolling contact fatigue of steels in hydrogen, and relevant processes occurring at tribo-interfaces. Important findings include significant effects of a small amount of oxygen and water in hydrogen on tribo-chemical processes at metal and polymer surfaces, additional effects by hydrogen, effects of high pressure at tribo-interfaces, and effects of contact conditions on hydrogen uptake at contacting surfaces.
