TRIBOLOGICAL Sl1JDY OF JATROPHA (Jatropha carcass L) OIL AS ECO-FRIENDL Y BOUNDARY LUBRICANT

The prospect of jatropha oil as lubricant oil for boundary lubrication application is
still not much studied yet. This research is mainly focused on enhancement of
tribological properties ofjatropha oil as ceo-friendly lubricant base stock. The work is
involving study on the effect of structural modification and additives addition to
tribological properties of jatropha oil. The objectives of the research are: (i) to
investigate friction, wear. and oxidation of jatropha oil, (ii) to synthesize and
investigate friction, wear, and oxidation of jatropha oil derivatives, and (iii) to
investigate the effects of anti-wear and antioxidant additives on friction, wear and
oxidation of jatropha oil. Friction and wear preventive properties of the oil were
examined by four ball method. Thermo-oxidative property of the oil was studied by
thermo-gravimetric analysis (TGA) method. Fourier transform infra-red (FTIR) and
nuclear magnetic resonance (NMR) were employed to study functional groups and
stmcture changes in the jatropha oil.
