THE INFLUENCE OF A TYPE OF DISPERSION PHASE ON THE TRIBOLOGICAL PROPERTIES OF LUBRICATING GREASES
Journal Title: Tribologia - Year 2012, Vol 246, Issue 6
Abstract
In this article, the author presents the results of investigations on the influence of the dispersion phase on the lubricating properties of selected lubricated compositions. For production lubricating greases, mineral, synthetic, and vegetable oil bases are thickened with modified silica to form AerosilR. The investigation of tribological properties were carried out for lubricating greases made on different oils bases and the obtained results were compared to account for the influence of the kind of dispersion phase on the value of research parameters. The results of investigations on the limiting load of wear, weld point, scuffing load, the limiting load of scuffing, and the limiting pressure of seizure were used for the estimation of tribological properties. Using the results of the tribological investigations, we were able to ascertain the most advantageous compositions for the antiwear properties of lubricating greases that influence vegetable oil; however, the best protections against anti-scuffing are mineral oils of pharmaceutical purity.
