摘要：
A phosphorus-free triazine-based organic molybdenum compound (DCDM) was designed and synthesized by using the click chemistry approach, and its friction-reducing and anti-wear properties were evaluated in PAO10 base oil. The results indicated that DCDM exhibited excellent tribological performance, with a reduction of approximately 35% in friction coefficient and about 46% in wear scar diameter, due to the synergy effect between Mo and S. Surface analysis by EDS and XPS revealed the formation of MoO3, Fe2(SO4)3, FeS, and MoS2 in the friction film. And it was furhter confirmed that the presence of MoS2 in the friction film contributed most significantly to the enhancement of the friction-reducing and anti-wear properties of the developed triazinebased organic molybdenum compound in PAO10 base oil.
