Hydrocarbon Lubricants Can Control Hydrogen Embrittlement. [PDF]
Sci Rep, 2020 AbstractWhile it is well known that during RCF tests the formation of nascent catalytic sites on the wear track can break down hydrocarbon molecules to release atomic hydrogen, the potential of the hydrogen environment in fuel cells to hydrocrack the hydrocarbon lubricant in high pressure rolling contacts has so far been ignored.
