Experimental Analysis on Tribological Behavior of Nano Based Bio-Lubricants using Four Ball Tribometer
Journal Title: Tribology in Industry - Year 2015, Vol 37, Issue 4
Abstract
The present work describes the tribological behavior of CuO, WS2 and TiO2 nano particles as an antiwear additive to a chemically modified rapeseed oil (CMRO). The tribological tests were run on a four ball tribometer. The variation of viscosity of various nano based biolubricants with respect to temperature is also estimated in accordance with ASTM D 445. The test results were compared with petroleum based synthetic lubricant (SAE20W40). The test results exhibited that CMRO with nano CuO has better tribological characteristics, smoother wear scar and higher viscosity compared to synthetic lubricant and other nano based biolubricants.
