Phase separation of phosphazene additives in perfluoropolyalkylether (PFPAE) lubricants is investigated as a function of additive concentration and lubricant layer thickness. The tribological behavior of various phosphazene additive/lubricant mixtures is evaluated using start/stop and constant speed drag testins. Near edge X-ray absorption fine structure (NEXAFS) is applied to investigate the presence of unsaturated carbon bonds at interfaces lubricated with a functionalized PFPAE and additives mixture.
