Humidity-dependent lubrication of highly loaded contacts by graphite and a structural transition to turbostratic carbon

Graphite, one of the oldest known dry lubricants, loses its friction-reducing properties in dry environments. Here, the authors show that this effect is associated with both chemical modifications of the surfaces and a structural transformation of the graphite to turbostratic carbon.
