WebIn order to calculate the hardness of the tribofilm from the nano-scratch results, we assumed that the AFM diamond tip acted as an abrasive to plough the tribofilm. The phosphorous-derived tribofilm formed from Fluid A was harder than the sulfur-derived tribofilm from Fluid B, and it was calculated that the phosphorous-derived tribofilm was …

WebMay 4, 2024 · ABSTRACT Tribofilms play a vital role in protecting lubricated surfaces in mechanical systems in motion. To date, understanding tribofilms has been mostly based on ex situ analysis. This research investigates the kinetics of a tribofilm formed on a pair of bearing steels (E52100). Strategically selected illuminative nanoparticles of NaYF4 were … WebThis tribofilm removal makes quantification of ZDDP tribofilm formation rate on non-ferrous surfaces under boundary lubrication conditions difficult. By contrast, under high shear stress EHL conditions, thick tribofilms formed without film removal with the tribofilm thickness being the greatest for steel, followed by Si 3 N 4 and then WC, with no tribofilm formation …
