Investigation of tribological properties of CuO/palm oil nanolubricant using pin-on-disc tribotester

It has been proposed that nanoparticles have the ability to enhance the tribological properties of lubricants. In the present research, the tribological properties of a palm-oil-based nanolubricant with copper (II) oxide (CuO) nanoparticles have been investigated experimentally using a pin-on-disc t...
