Anti-Wear and Friction-Reduction Properties and Mechanism of Organic Molybdenum Compounds and Zinc Dialkyldithiophosphate (ZnDDP)in Lipid Synthetic Oil
油溶性有机钼与二烷基二硫代磷酸锌(ZnDDP)在酯类油中的协同抗磨减摩性能及机理研究

Friction and wear properties of two kinds of organic molybdenum compounds were evaluated on a four-ball friction and wear tester.Pentaerythritol ester as stock oil containing organic molybdenum such as molybdenum dialkyldithiophosphate(MoDDP),molybdenum dialkyldithiocarbamate(MoDTC) and zinc dialkyldithiophosphate(ZnDDP).The morphologies of the worn surfaces were observed using SEM.The chemical states of several typical elements on the worn surfaces were examined by XPS.The composite of oil-soluble organic ...
