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.
Claims30
A method for reducing rate of surface current induced degradation for components in a hydraulic system, the hydraulic system having components exposed to phosphate-ester-based hydraulic fluid, the method comprising the step of:
- adding a redox couple to the hydraulic fluid.
A hydraulic system comprising:
- a phosphate-ester-based hydraulic fluid, and
- a redox couple.
A hydraulic fluid for use in a hydraulic system, the fluid comprising:
- a phosphate-ester-based compound, and
- a redox couple.
An additive for a hydraulic fluid comprising a redox couple.
