Synergistic effect between h-BN and MoS2 for excellent lubrication of solid lubricant coating for high-temperature, open-air-system applications

Friction
High-temperature solid lubricant coatings with decent lubrication performance are essential in critical processes of metal forming and aerospace. However, their preparation is formidably challenging due to the harsh working conditions.

Flow‐Induced Long‐Term Stable Slippery Surfaces

Advanced Science, 2019
Slippery lubricant‐infused surfaces allow easy removal of liquid droplets on surfaces. They consist of textured or porous substrates infiltrated with a chemically compatible lubricant. Capillary forces help to keep the lubricant in place.

Phenomenological Theory for the Melting of a Thin Lubricant Film between Two Atomically Smooth Solid Surfaces [PDF]

, 2010
A thermodynamic model is developed for the melting of an ultrathin lubricant film squeezed between two atomically smooth solid surfaces. To describe the state of lubricant, an excess volume parameter is introduced; it appears due to the chaos in the ...
