The influence of various grease compositions and silver nanoparticle additives on electrically induced rolling-element bearing damage

Friction
Leakage currents accelerate surface degradation of metal contacts via small scale arcing across lubricating films, but recent observations suggest that metallic nanoparticle additives in lubricants may be useful to improve contact performance.

Conductive and tribological properties of TiN-Ag composite coatings under grease lubrication

Friction, 2020
TiN-Ag composite coatings were prepared by pulsed bias arc ion plating. X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS) were applied to analyze the compositions of the coatings.

Study of instantaneous starvation at a finite-length line contact [PDF]

Jurnal Tribologi, 2019
Starvation phenomenon widely exists in the non-conforming contacts when high-viscosity lubricating oil or greases are used. However, most of the work focuses on the steady state starvation, and the phenomenon of instantaneous starvation is not well ...
