Performance of castor based biodiesel during tribological characterization at different load

Abstract In this study, friction and wear analysis of castor oil-based biodiesel was conducted. The B0, B100, B10, B20 and B50 are the samples considered for the test. The test was performed on pin-on-disc machine at different loads 40 N and 100 N. The sliding speed of 150 rpm was considered constant and ambient temperature was taken during the analysis. It has been observed that the coefficient of friction increases with the applied load. The diesel was taken as the reference oil. The diesel (B0) shows more coefficient of friction and wear at both the loads. The minimum coefficient of friction and less wear of the surface was obtained at 100% biodiesel (B100). The increment of biodiesel blends showed better results in reducing friction, and wear of the parts during their sliding contact. Biodiesel is having better lubricity as compared to diesel and could be implemented in the diesel engine as a lubricant in near future.
