Abstract

Vinyltrimethoxysilane monomer and oligomer film former were investigated as oil additives in terms of their tribological as well as their tribochemical behavior. The additives were dissolved in mineral oil and tested in different tribometers to evaluate the influences on friction, wear, lubricating film thickness and to track the film formation. The obtained reaction films from the friction tests were analyzed upon their morphology and chemical structure. It was found that organosilane/-siloxane molecules can deposit in a multi-layered film architecture, consisting of a polymeric layer on top of a glass-like coating. The glass-like tribofilm is adhesive, while the polymeric layer is weakly cross-linked and viscous. Depending on film structure, friction and wear can be reduced by more than 40%.
