摘要：
The tribological properties of attapulgite/oil-soluble nano-Cu composite lubricating additive were investigated by a SRV-IV friction wear tester. The worn surfaces were characterized by SEM and XPS. The results show that the two single additives can both improve the tribological properties of the base oil for a steel-steel friction pair,whereas the composite lubricating additive possesses more excellent friction-reduction and anti-wear properties than the single additives. The higher the load is, the better tribological properties the composite lubricating additive will show. In the effect of composite additive, a compact and smooth protective tribofilm composed by FeS2,Fe2O3,SiO2,Cu,FeOOH and organic compounds was formed on the worn surface. © 2016, Journal of Materials Engineering.
