Wear Resistance Characteristic of Vegetable Oil

Abstract

The main source for lubricant oils is mineral oils, but the source of mineral oils are depleting from day to day and it is also a major cause for environmental pollution in the world. This aim of research is to introduce vegetable oil as an alternative source of lubricant oil in industrial applications. In this study, we measured the physical properties of Jatropha, palm fatty acid distillate (PFAD) and empty fruit bunches. All experiment were done according to the American Society for Testing and Materials (ASTM) condition, method B and with the use of four-ball tribotester, CCD camera, microscope and viscometer to obtain results. The test oils were measured of their coefficient of friction, wear, viscosity and flash temperature parameter. To evaluate the results, the same conditions were applied for all experiments with the use of engine and hydraulic mineral oil. The results showed that the anti-friction ability of Jatropha oil and PFAD was higher than the engine and hydraulic mineral oils.

Tribological Performance and Rheological Properties of Engine Oil with Graphene Nano-Additives

“…percent, a resilient hydrodynamic lubricant film forms, reducing WSD and friction coefficient. Low concentrations of GN tend to have higher surface-tovolume ratios [33,34]. Due to this volume, amalgamation, uniformity, friction, and WSD increased.…”
