Abstract : Samples of materials containing organic sulfonates, phenylamines, diamines, thiophosphates, phosphates, modified fatty acids, or a combination of one or more of these compounds were obtained for screening tests to determine the relative effectiveness of these materials as corrosion-inhibiting additives for mineral oil-base lubricants. The results of these tests indicated that the most effective corrosion-inhibiting additive was stearoyl sarcosine. Experimental lubricants for weapons were formulated with stearoyl sarcosine and antiwear additives in a mineral oil-base fluid. An optimum lubricant formulation was established that exceeds the lubrication properties of MIL-L-46000A (Military Specification, 'Lubricating Oil, Semifluid - Automatic Weapons') and that approaches the high-humidity, corrosion-inhibiting characteristics of MIL-L-46000A. However, the salt-spray resistance properties of this formulation were inferior to those of MIL-L-46000A. (Author)
