Description
Summary:This study compared the tribological evaluation of chemically modified rapeseed oil as a potential biodegradable automotive lubricant with and without nano- and microscale titanium dioxide (TiO 2 ) particles, focusing on the influence of TiO 2 particles to improve the friction reduction and antiwear characteristics of chemically modified rapeseed oil. TiO 2 nano- and microscale particles of anatase phase and rutile phase were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Further, the analysis of chemically modified rapeseed oil with and without TiO 2 additives was carried out to determine its tribological behavior using a pin-on-disc tribometer. The experimental results showed that the addition of TiO 2 nanoparticles exhibited good friction reduction and antiwear properties compared with the addition of microscale TiO 2 and without TiO 2 additives to chemically modified rapeseed oil. Nanoscale TiO 2 is suitable as an antiwear additive in chemically modified rapeseed oil.
