Hydrocarbon Lubricants Can Control Hydrogen Embrittlement. [PDF]

open access: yesSci 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.

Hydrogen embrittlement in metallic nanowires. [PDF]

open access: yesNat Commun, 2019
AbstractAlthough hydrogen embrittlement has been observed and extensively studied in a wide variety of metals and alloys, there still exist controversies over the underlying mechanisms and a fundamental understanding of hydrogen embrittlement in nanostructures is almost non-existent.

The Phenomenon of Hydrogen Embrittlement in High-Strength Bolts [PDF]

open access: yesArchives of Metallurgy and Materials, 2023
The hydrogen embrittlement of metals is caused by the penetration and accumulation of hydrogen atoms inside the metal. The failure of the product due to hydrogen embrittlement is delayed in time and does not occur immediately after its manufacture, but ...
