dc.description.abstractResearch has shown that side/end products of phosphorus and sulfur compounds in engine oils reduce effective life of exhaust catalysts of automobiles resulting in harmful emissions. Thus environmental regulations have been imposed on phosphorus levels in engine oils. The main source of phosphorus in today's oils is the indispensable antiwear agent Zinc Dialkyl Dithiophosphate (ZDDP). To find cost-effective non-phosphorus substitute has not proven fruitful. A unique way of reducing phosphorus or ZDDP level while maintaining good antiwear performance has been achieved by introduction of a novel additive FeF3 along with ZDDP. It appears that the interactions between FeF3 and ZDDP are strong enough not only in overshadowing the undesired interactions between ZDDP and additive package but result in more 'protective film' than the usual tribo-film from ZDDP decomposition products. The objective of this research is to examine the chemical interactions between ZDDP and FeF3 underlying their improved wear performance.en_US
