AbstractDry film lubricants are used extensively in military and commercial aircraft engines to prevent galling, fretting and seizing and to aid in maintenance disassembly and re-assembly. Most dry film lubricants contain volatile organic compounds as carriersolvents. Many also contain lead compounds for added endurance life and antimony oxide as a corrosion inhibitor. Graphite is often used as a lubricant by itself or with other solid lubricants. Each of these components poses an environmental hazard andtheir use must be discontinued. TRI/Austin proposes to develop a water-based system containing alternative lubricants and additives that will be environmentally and toxicologically benign, meets the requirements of MIL-L-23398 and MIL-L-46147, and can beapplied using standard procedures with minimal impact to the Navy. The technical challenge to be faced in this development involves obtaining an adequate dispersion of the lubricant in the water-binder solution so that coating segregation does not occurduring binder cure. The proposed new dry film lubricant will be environmentally and toxicologically benign without deleterious impact to existing Navy field practices.
