Over-based calcium sulfonates， dibenzyldisulfide and tricresyl phosphates were employed as additives by multi-or single use. It was found that reduction of wear and increase of friction at the same time，which is desirable for CVT f1uids，can be achieved by adequate formulation of additives. TOF-SIMS analysis of the wear track was conducted to understand the chemical composition of the boundary lubrication film generated by the tribochemical reactions of the additives. The depth profile of the boundary lubrication film was also acquired by an etching technique. The analysis revealed that the profile of the boundary lubrication film depends on the film precursors，the additive(s). It was suggested that wear and friction can be controlled
independently by designing the boundary lubrication film，which derived from additive(s).
