Experiments were conducted to establish the capabilities of a fatty acid (stearic) as an additive for lubrication of steel surfaces at high sliding velocities (75 to 7000 ft per min) with severe loading (169 to 1543 grams, initial Hertz surface stress, 108,000 to 194,000 lb per sq in.) and to determine the efficacy of prepared oxide films in this type of lubrication.
