Nowadays, nanoparticles are extensively employed by mixing them with oils to improve the matting bodies’ tribological properties, especially in manufacturing operations that encompass the generation of high temperature, residual stresses and cutting forces that directly affect the engineering part’s life, therefore, using nano-lubricated oils becomes a vital tool to reduce these effects. The current investigation is concerned with resolving tribological behavior issues for two lubricant oils, such as 7701 and 144.mg oils, throughout adding different Nanoparticles types. The present study’s primary purpose is to explore the tribological behavior of AA1060 aluminum alloy under dry and lubricated conditions by adding various weight percentages of nanoparticles to 7701 and 144.mg oils. molybdenum disulfide (MoS2) and copper oxide (CuO) nanoparticles with five concentrations vary as follows (0.2, 0.4, 0.6, 0.8, 1.0, and 1.2) %wt. were dispersed in 7701 and 144.mg oils to prepare the nano lubricant additives. This paper’s findings reveal a remeakable improvement in coefficient of friction and wear rate due to adding nanoparticles powder to the oil compared to dry and base oil conditions. The optimal condition for coefficient of friction and wear rate was observed at 1%wt. of both nanoparticles and hybrid lubricant additives.
