Influence of the amount of metal-containing additive on performance characteristics of lubricant based on rapeseed oil

Abstract

The paper exposes experimental results of the performance characteristics (coefficient of friction, contact temperature and wear) of the biolubricant based on rapeseed oil. The amount of commercial metal-containing additive in formulated lubricant was 1, 1.5, 3 and 5 %. All results were compared with the results obtained for the base rapeseed oil. They showed that the metal-containing additive in rapeseed oil reduced all characteristics (coefficient of friction, contact temperature and wear). It was also found that the dependence of all characteristics on the amount of additive is nonlinear and that there is an optimal value of it.
