Effect of lubricant composition and tribological contact conditions on permeation of hydrogen into steel rubbing surfaces
Description preview
Premature failures of machine elements, such as bearings and gears, in lubricated machines have often been linked to the permeation of hydrogen into contacting surfaces during rubbing. Presence of mobile hydrogen in hard steels is known to lead to embrittlement, and hence shorter fatigue lifetimes of the affected components. Perhaps the best-known…
