A multi-technique approach of tribofilm characterisation
Thin Solid Films, 2004 The characterization of tribofilms has already been studied by various surface analysis tools for many years. The analytical techniques usually performed on this kind of samples are X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES) and X-ray absorption near-edge structure (XANES).

Chemistry of ZDDP Tribofilm by ToF-SIMS
Tribology Letters, 2004Time-of-flight secondary ion mass spectrometry (ToF-SIMS) (static and dynamic modes) has been applied to chemical characterization of zinc dithiophosphate additives tribofilm. Main result concerns insights in the spatial distribution of phosphate and sulphide species in the whole tribofilm thickness, at a sub-micrometer scale.

Tribofilm formation of lightly loaded self mated alumina contacts
Wear, 2012 A tribofilm is formed on alumina surfaces that have been slid against alumina surfaces. The tribofilm is formed by alumina wear particles that have been ground, agglomerated and tribosintered to a film.

Influence of Steel Surface Composition on ZDDP Tribofilm Growth Using Ion Implantation [PDF]
Tribology Letters, 2021 This paper examines the influence of steel surface composition on antiwear tribofilm formation by ion-implanting typical steel alloying elements, Ni, Mo, Cr, V and W, into AISI 52100 bearing steel surfaces.

Formation and Characterization of Tribofilms
Journal of Tribology, 2008Fundamentals of tribofilm formation and their properties were studied. In order to understand the effects of lubricants on tribofilms, four base oils were investigated. Lubricants include castor oil, polyethylene glycol, mineral oil, and margarine.

Formation and Nature of Carbon-Containing Tribofilms
ACS Applied Materials & Interfaces, 2019Minimizing friction and wear at a rubbing interface continues to be a challenge and has resulted in the recent surge toward the use of coatings such as diamond-like carbon (DLC) on machine components. The problem with the coating approach is the limitation of coating wear life. Here, we report a lubrication approach in which lubricious, wear-protective

Role of tribofilms in wear protection
Tribology International, 2016Abstract Engine valve train wear protection has been observed despite the absence of classical tribofilm formation. This was found with a lubricant containing zinc dialkyldithiophosphate (ZDDP), despite conventional understanding that ZDDP reduces wear by forming a thick, protective, inorganic phosphate tribofilm. We suggest that an antiwear additive

Mass balance of the tribofilm in lubricated systems
Tribology International, 2021Abstract The efficiency of the lubrication systems varies during the time of use of each batch of lubricant, increasing wear and friction in the lubricated system. In this work, transient mass balances of the lubricant precursors that form the protective film in lubricated systems, the substances that constitute the deposited film, and the waste ...
