Achieving superlubricity in DLC films by controlling bulk, surface, and tribochemistry [PDF]
, 2014 Superlubricity refers to a sliding regime in which contacting surfaces move over one another without generating much adhesion or friction [1]. From a practical application point of view, this will be the most ideal tribological situation for many moving ...

Modelling Tribochemical Reactions of Lubricants in the UHV Analytical Tribometer
Tribology Online, 2015 Gas Phase Lubrication (GPL) is used here to lubricate counterparts of a tribological system with a partial pressure of a gas. Because the rheological contribution (Hydrodynamic and EHL) of gas is practically negligible, the role of tribochemical ...
