A four‐ball machine was used to evaluate the antiwear performance of three kinds of organomolybdenum compounds — molybdenum dialkyldithiophosphate (MoDDP), molybdenum dialkyldithiocarbamate (MoDTC), and sulphur‐ and phosphorus‐free organomolybdenum — and their antiwear synergistic effect with a zinc dialkyldithiophosphate (ZnDDP). The results indicate that the three organomolybdenum compounds have good antiwear properties, especially MoDDP, and the organomolybdenum compound — especially MoDTC and sulphur‐ and phosphorus‐free organomolybdenum compound — exhibit good antiwear synergisms with ZnDDP in a paraffin base oil.
