A review of use of nanoparticle additives in lubricants to improve its tribological properties

Abstract

The improvement of the topological properties in contacts surfaces has been drawn the attention of many commercial firms to reduce energy waste resulting from the influence of friction and wear in combustion engines. These motivations were sufficient for adding nanoparticles upon lubricants to improve their performances. Analysis of nano specimens' experimental tests revealed the enhancement of tribological properties to reduce friction and wear increasing, especially in cutting fluid performance. The operations are elementary and smooth, with the most extended cutting tools life and saving fuel consumption. Nanoparticles additives have been detected by nano techniques to evaluate the Nano tests and determined the morphology properties of nano mixture lubricant to developing or modify the fats. The nanoparticles fill into the cavities of the molecular surface so that forms a nanofilm that insulates, rub parts and slips quickly and softly due to the low value of the coefficient of friction. The nanofilm mechanism has contributed to improving topological characteristics, exceptionally reducing the emission of friction temperatures and preventing gradual deformation of material at solid surfaces, leading to inhibit material failure or loss of functionality. Also, the effect of Bio-lubricant with Nanoparticle additive was investigated.
