“…Replacement of the oxygen atom of the Mo compound by a sulphur atom is considered t o be a possible reason for this effect. [15][16][17] The data obtained in the present study suggest that sulphur EP compounds in combination with soluble Mo compounds do not all produce synergistic effect in antifriction property. It appears to depend on the chemistry of the sulphur compounds, and is probably related to the availability of an optimum level of reactive sulphur from the EP compounds at the prevailing operating conditions.…”

Antifriction and antiwear performance of three soluble molyb&num (Mo) compounds (Mo dithiophosphate, Mo dithiocarbamate and Mo amine complex) and four sulphur-containing EP additives (sulphurised isobutylene, dibenzyl disulphide, sulphurised fat and synthesised ethylene sulphur derivative) havebeen studied, alone and in combination, using a n SRV test rig. The additive behaviour in Combination has been found to be selective, and dependent on the chemistry and ratio of the additive components. Certain sulphur EP additives in combination withMo compounds have exhibited a synergistic effect. The antifriction performance of additives, in general, has been found to be further enhanced at higher test temperatures. However, a reduction in antiwear property has been noticed.
