The effect of load in a contact with boundary lubrication [PDF]
The effect of the transition load on the wear in a contact with boundary lubrication was investigated. An experimental method was developed for this purpose, and parameters affecting the boundary lubrication under industrial operating conditions were ...

Averaged Reynolds Equation for Flows between Rough Surfaces in Sliding Motion [PDF]
, 2002 The flow between rough surfaces in sliding motion with contacts between these surfaces, is analyzed through the volume averaging method. Assuming a Reynolds (lubrication) approximation at the roughness scale, an average flow model is obtained combining ...

ZDDP Tribofilm Formation on Non-Ferrous Surfaces
Tribology Online, 2020 The current trend for using lower viscosity lubricants with the aim of improving fuel economy of mechanical systems means that machine components are required to operate for longer periods in thin oil film, boundary and mixed lubrication conditions ...

Boundary lubrication and maxillofacial prosthetic polydimethylsiloxanes
Biomaterials, 1991 Polydimethylsiloxanes exhibit hydrophobic behaviour and poor wettability. These features impose some problems with the clinical performance of the material when used for the construction of intraoral and extraoral facial prostheses. Surface active agents were added to modify the surface energy of the polydimethylsiloxane and contact angle measurements ...

Thin film lubrication in the past 20 years
Friction, 2016 Thin film lubrication (TFL), a lubrication regime that fills the gap between boundary lubrication (BL) and elastohydrodynamic lubrication (EHL) regimes, was proposed 20 years ago.
