Wear Behavior of Carbon Coated Copper Nanoparticles as an Additive to Bio-based Lubricant

Abstract

Abstract-This study compares the antiwear (AW) characteristics of bio-based lubricant by addition of carbon-coated copper nanoparticles with the case of non-coated copper nanoparticles, determining the effect of carbon coating. For wear elemental analysis in controlled engine environment, a four-cylinder motoring engine test rig was used. The results showed that carbon-coated nanoparticles helped in wear protection of engine parts.
