Comparison of Tribological Characteristics of Carbon-based Nano Lubricants
To decrease the friction coefficient and wear rate,many researchers have tried to improve the tribological characteristics of the lubricants.One of the approaches is simply adding additives into the base lubricant to change the properties.This method has been widely applied in lubrication engineering for a quite long time and contributed to the increase of the ability of lubricants.Recently nanoparticles have been emerged as a new kind of additives because of their size,shape and other properties.Nano lubricant is a new kind of engineering lubricant made of nanoparticles,dispersant and base oil.In this study,carbon-based nanoparticles and nano fibers such as graphite,carbon black,GNF(Graphite nanofiber) and MWCNT(Multi-walled carbon nano tube) were used to fabricate nano lubricants for enhancing the tribological properties and lubrication characteristics.To investigate the physical and tribological properties of nano lubricants,the friction coefficients and the temperatures were measured with disk-on-disk tribotester in the range up to 3,000 N.The surfaces of the fixed plates were observed by scanning electron microscope (SEM) to analyze the characteristics of the friction surfaces.
