REDUCTION OF ELECTROCHEMICAL SURFACE DEGRADATION CAUSED BY LIQUID FLOW USING REDOX COUPLES

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method for reducing the rate of surface current degradation of components inf a hydraulic system exposed to phosphate-ester-based hydraulic fluid. Method comprises adding a redox couple to the hydraulic fluid, wherein the redox couple comprises a sandwich compound of the formula: M(A_r)₂^+/0, wherein M is a transition metal and A_r is an aryl compound. Invention also relates to a hydraulic system, a hydraulic fluid and an additive to the hydraulic fluid using the composition used above.;EFFECT: additives used can reduce surface currents caused by electrokinetic processes associated with operating pressure inside modern hydraulic systems.;14 cl, 2 dwg, 2 ex
