Method for maintaining antiwear performance of turbine oils containing polymerized amine antioxidants and for improving the deposit formation resistance performance of turbine oils containing monomeric and/or polymeric antioxidants

摘要

The antiwear performance of turbine oils containing polymerized amine antioxidants and antiwear additives is maintained at or enhanced beyond the level as that of turbine oils containing monomeric amine antioxidants by employing as the antiwear additive a resorcinol bis(diphenylphosphate) (RDP). The deposit formation resistance performance of turbine oils containing monomeric and/or polymeric amine antioxidant is improved by employing RDP.
