Abstract
The present disclosure relates to methods, systems, hydraulic fluids and additives for reducing the rate of surface current degradation for components in a hydraulic system, wherein the hydraulic system is exposed to phosphate-ester-based hydraulic fluid.
Claims20
An hydraulic fluid for use in an hydraulic fluid system, said hydraulic fluid comprising:
- a phosphate-ester-based hydraulic fluid comprising an additive, with said additive comprising a redox couple.
An hydraulic fluid comprising a redox couple.
A method for reducing rate of surface current induced degradation for components in an hydraulic system, the method comprising the step of:
- adding an hydraulic fluid to the hydraulic system, said hydraulic fluid comprising an additive, said additive comprising:
- a redox couple.
