abstract: Jatropha oil has been known as alternative substitute for diesel fuel but its function as lubricant is not much known yet. In this work, wear preventive characteristic of jatropha oil has been investigated in order to find its potential as alternative lubricant base stock and lubricant substituent. Four ball wear test method was employed for this occasion. The results show that crude jatropha oil has comparable wear preventive capability to mineral oil. When treated as lubricant substituent, blending of 25 jatropha oil to mineral oil was able to reduce 33 wear of the mineral oil. However, wear was increased with 50 and 75 addition of jatropha oil. Wear coefficient was found in the range of 6.05�10-11-8.60�10-10. Scanning electron microscopy analysis showed adhesive, abrasive and fatigue wear mechanisms were taken place during the sliding. EDX analysis shows steel ball lubricated with higher mineral oil content forms strong organo-iron compound layer and steel lubricated with higher jatropha oil content forms a typical metallic iron carbon layer. Based on these results we conclude that jatropha oil has great potential to be used as lubricant base stock or as lubricant substituent. © 2011 Asian Network for Scientific Information.
