Influence of roughness on ZDDP tribofilm formation in boundary lubricated fretting [PDF]
, 2012 Influence of initial surface topography on tribofilm formation in ZDDP lubricated contact was analysed. A small displacement fretting tests with sinusoidal motion were carried out in classical sphere/plane configuration.

Transient Nanoscale Tribofilm Growth: Analytical Prediction and Measurement [PDF]
Applied Sciences, 2021 A new method for the simultaneous in situ measurement and characterisation of molybdenum-based tribofilms is presented, based on lateral force microscopy. The simultaneity of measurements is crucial for a fundamental understanding of the tribochemical phenomena.

Characterization of ZDDP and ionic liquid tribofilms on non-metallic coatings providing insights of tribofilm formation mechanisms [PDF]
Wear, 2015 Abstract Lubricant anti-wear additives are known to chemically interact with metallic surfaces to form a self-healing, wear-protection tribofilm. Their interactions with non-metallic surfaces are however less understood. Here we report recent findings on whether and how a zinc dialkyldithiophosphate (ZDDP) and a phosphonium–organophosphate ionic ...
