Review of tribological properties of nanoparticle-based lubricants and their hybrids and composites

Due to their encouraging results,nanolubricants have been revolutionary in the field of lubrication.The degree,to which the new material may improve the tribology,energy savings,and durability,is a crucial consideration for any new additive to a conventional lubricant.The results of the earlier research on carbon,metal,metal oxide,and their composites and hybrid nanolubricants as well as their effects on tribology,are summarized in this review paper.The most popular measuring methodologies,the tribology results for lubricants with an oil base,biodegradable base,and a water base,as well as the reasons that explain these tribological advancements,are all included in this study.Finally,prospects for more study in this area are emphasized.
