Abstract : A successful search was made for petroleum-base hydraulic fluids with rust-inhibiting qualities adequate to prevent rusting in submarine hydraulic systems contaminated with seawater. Fluids of two types were found with considerably greater rust-inhibiting ability than currently used Navy hydraulic fluids. The type of fluid giving the better rust inhibition deviated from present hydraulic fluid specification requirements in that it emulsified readily with contaminating seawater, whereas the second type did not. Other necessary properties of both fluid types were satisfactory. Feasibility of using the emulsifying-type fluid in submarine hydraulic systems was shown by 1000 hr of satisfactory operation using a hydraulic system mock-up with full scale submarine system components in the presence of 10% sea-water contamination. Technical specification requirements for this type fluid were drawn up.
