Wear behaviour and tribochemical reactions of low molecular dicarboxylic acid esters under boundary lubrication of the steel-on-steel mating elements.

Abstract

#This research aims to study the mechanism of action and interaction of certain carboxylic acid esters in contact with steel surfaces. These esters are used as primary lubricants and have been tested for this purpose. The research followed an experimental methodology and included an introduction to the study topic, two chapters, and a conclusion. The first chapter addressed the corrosion resistance properties of the diester under boundary lubrication in the steel system. The second chapter focused on the surface analysis of the chemical reaction products using FTIR microscopy. The conclusion included the most important results, including the presence of new absorption bands at 1716 cm-1 on steel substrates belonging to organometallic compounds containing the carbonyl group.
