PCMO Lubricant Friction Modifier Performance Durability - Extended Tribology Studies

New tribological bench tests were designed using the Plint TE-77and MTM to measure FM durability. GMO, MoDTC & Experimental EXP-OFM were studied. Experiments were performed on formed tribofilms after standard testing during subsequent oil exchanges (FM oil / non-FM oil / FM oil) that measuring the loss with non-FM and gain with new with new FM oil.  Next, FM's are studied with continued isothermal constant load testing for several days in the tribology test equipment. There is a surprising retention of friction reduction possible with organic friction modifiers. The data shows a constant friction reduction of organic FMs while the high performing MoDTC degrades with extended test time. For this study, FT-IR and SEM X-ray measurements were then made in order to gain molecular information of performance degradation.
