Corrosion Preventing Characteristics of Military Hydraulic Fluids

Hydraulic systems are widely used in a variety of military applications such as aircraft, ground vehicles, and weapon systems. The impact of corrosion on hydraulic systems and its components has been identified but is often not recognized¹. Project collaboration between the U.S. Army Research Lab, U.S. Army Corrosion Office, and Concurrent Technologies Corporation identified the most critical corrosion issues found in hydraulic systems to be hoses, hose end fittings, actuator arms, pistons, cylinders, and rams.
