Annotation:

We studied the influence of the dispersion medium and the base number of the thickener on tribological characteristics of sulphonate plastic lubricants. The following parameters were chosen for the study: the wear scar diameter, critical load and welding load. It was found that the lubricant based on P-40 oil showed best aggregate tribological characteristics, which significantly reduces the cost of lubricant. According to the research results we can conclude that antiwear and extreme pressure properties improve with increased base number of the thickener.
