The goal of this paper is to investigate the effect of different concentrations of nano-lubricants on the friction and wear of a disk- on- disk test setup. The uniquely developed nano-particles used in this study are CuO and have been proven to be exceptionally stable. Existing literature also suggests that CuO particles may be able to enhance lubricant performance in the boundary lubrication regime. A disk- on- disk test setup used in this study can measure the friction coefficient and wear using torque and load sensors. The tested samples are submerged in a small reservoir of the nano-lubricant. The wear and possible mending of the surfaces is evaluated by a surface profilometer and weighing the samples before and after testing. Experiments have been carried out for lubricants with different concentration of additives in various rotational velocity and loads.
