Operability of combat and support equipment can be seriously compromised by rusting of power train components. As a preventative measure, most lubricants in the Army Supply System are rust inhibited. Sulfonates, such as the petroleum sulfonates and salts of dinonylnaphthalenesulfonic acid, have proven to be effective rust preventatives for Army lubricants, however, their use is limited due to their high temperature instability and viscosity. New rust inhibitor systems are needed for formulation into a variety of fluids such as turbine engine oils, aircraft hydraulic fluids and the newer synthetic nonhydrocarbon fluids. A basic understanding of the rust inhibition mechanism is needed in order to accomplish this task and to keep pace with potential rust problems associated with advanced Army systems.
