Abstract

Since the 1970s more attention has been paid to biodegradable lubricants as a way of reducing the pollution caused by lubricants with a mineral oil base. This concern has promoted the use of vegetable oils as alternative base oils. This paper reports on a study of the effect of phosphate esters containing the benzotriazole group as additives in rapeseed oil (RSO), tests being carried out using a standard four‐ball tester. The results show that these additives produce good antiwear performance and load‐carrying capacity compared with RSO alone. Surface analysis of the worn halls was carried out using X‐ray photoelectron spectroscopy. The tribological mechanism is discussed on the basis of the experimental results.
