Abstract. The effect of phosphorus-containing additives on the performance properties of alkylphenolate greases based on a domestic thickener has been studied. The positive effect of surfactants on the performance properties of alkylphenolate grease is shown. It was found that the addition of 3% tributyl phosphate by weight improves the anti-wear properties of the grease (the diameter of the wear spot decreased from 0.53 to 0.45 mm). At the same time, the addition of 3% by weight of the DF-11k additive makes it possible to reduce the diameter of the wear spot to 0.49 mm while simultaneously increasing the critical load and welding load.
