Soluble Phosphorus-Based Compounds As Anti-Wear Additives For Perfluoropolyether Lubricants

New soluble additives were synthesized to act as anti-wear for perfluoropolyether oils. The tribological properties of the formulations of these phosphorus-containing compounds in different base oils have been evaluated by a Falex four ball test machine and by an Optimol SRV oscillating friction and wear tester. The results obtained, object of the present work, clearly show that these additives are able to significantly reduce the wear of PFPE oils (up to 50% reduction).
