Effect of Friction Modifiers on Physico‐Chemical and Tribological Properties of Industrial Oils

ABSTRACT Lubricant composition plays a crucial role in reducing wear and friction between moving components, thereby ensuring the smooth operation and protecting critical components of industrial machinery. Friction modifiers, as key additives, play a significant role in lowering the coefficient of friction and improving the energy efficiency of lubricants. In this study, we investigated the influence of friction modifier chemistry and concentration on the physico‐chemical and tribological properties of industrial lubricating oil. Results demonstrated that increasing the friction modifier concentration effectively reduces the friction coefficient in tribological tests and enhances the elastohydrodynamic film thickness. Furthermore, the study highlights the significant role of surface temperature in activating the friction modifier. These findings provide valuable insights for the design of energy‐efficient lubricants with optimised performance characteristics.
