An organic tungstic additive without sulfur and phosphorus was synthesized.The antiwear and friction reducing properties and synergistic effects of nonsulfur and phosphorus organic tungsten and zinc dialkyldithiophosphate (ZDDP) in polyalphaolefin base oil were investigated by a fourball tester.The synergistic antiwear mechanism of nonsulfur and phosphorus organic tungsten and ZDDP were studied by scanning electron microscopy.The results show that the synthesized nonsulfur and phosphorus organic tungsten has a certain friction reducing and antiwear effect in the base oil under low load,but the friction reducing and antiwear performance is poor under high load.The nonsulfur and phosphorus organic tungsten exhibits excellent antiwear synergy effect with ZDDP,and can withstand high working load.The synergistic effect of nonsulfur and phosphorus organic tungsten and ZDDP is the result of the formation of compound containing S and W protective film on the friction surface under high temperature friction conditions.
