520 ⊔ ⊔ ‡aTests were conducted in the NASA spinning-torque apparatus to determine the effect of lubricant additives on the torque of a ball spinning in a nonconforming groove. The base lubricant was a synthetic paraffinic oil to which were added 0.1, 1. 0, and 10 volume percent of either an antiwear or EP additive. The additives used were stearic acid, oleic acid, oleyl phosphate, oleyl phosphite, and zinc dithiophosphate. Under the test conditions, elastohydrodynamic lubrication prevailed with no significant surface interaction. The addition of the antiwear or EP additives in several concentrations to the synthetic paraffinic oil did not change the spinning torque over that obtained with the base fluid. The viscoelastic properties of the base fluid were not changed by the additives tested.--P. [i].
