The article presents studies on the dependence of sedimentation resistance of the anti-wear additive solid component for marine diesel trunk-type internal combustion engines on the technological conditions of its manufacturing. A friction modifier, molybdenum diselenide, which has optimal anti-wear properties, was selected as a solid component. The authors consider the process of sedimentation of a given substance, stabilized in the volume of an additive solution with unsaturated acids, at different times of rotary stirring, and under the influence of subsequent treatment of the prepared solution with ultrasound. The mass of the solution solid component is studied as irretrievably precipitated over various periods of storage time of the additive solutions, subjected to rotary stirring and additional ultrasonic treatment. The recommended storage time of the considered anti-wear additive with a 10% content of molybdenum diselenide has been established.
