Summary

In this investigation, an optimized nano Fe 3 O 4 based ferromagnetic lubricant was created by utilizing mechanical and ultrasonic blending. Fe 3 O 4 nanoparticles in varying amounts and percentages have been dispersed in Karanja base oil containing oleic acid as a surfactant. The wear mark diameter received in the four-ball test with the set standard was viewed as the output effect in the experiment. Thereafter, the obtained results showed the anti-wear functionality of the enhanced Karanja oil with ferromagnetic particles to be used as a lubricant. The stabilities of the lubricant sample were evaluated by calculating the sedimentation rate for a period of four months.
