Abstract
The physicochemical and tribological parameters of the ash-free additives obtained in the laboratory are given. It is shown that they have high extreme pressure properties and low ash content. The results of comparative laboratory tests of tribo-engineering characteristics of new additives of Russian and foreign production are presented. It is found out that the new additives in terms of maximum load capacity are not worse than imported analogues and can be used to increase the extreme pressure properties of lubricants for various purposes (including ash-free ones) instead of their imported analogues. A pilot batch of additives containing 45% sulfur is prepared and tested.
