CORROSION OF SERVO VALVES BY AN ELECTROKINETIC STREAMING CURRENT.

Abstract

Corrosion driven by electrokinetic currents was found to be responsible for damage to steel servo valves operating in phosphate ester fluids. Calculations and test results supporting this conclusion and measurements of the electrokinetic and electrochemical properties of the steel to fluid interface are described. Possible fluid additives for reducing the damage are discussed.
