Preparation and Tribological of 8-Hydroxyquinolinato Cerium

Abstract:

A new solid cerium complex, was synthesized by 8-hydroxyquinoline and cerium nitrate in the ethanol-aqueous solution. The complex was characterized by elemental analysis and FTIR. The results indicate that the complex is Ce(C₉H₆NO)₃. The tribological properties of the Ce(C₉H₆NO)₃ particles as additive in paraffin oil was investigatedon MRS-10A four-ball tester, the results indicate that Ce(C₉H₆NO)₃ particles as additive can be effective in improving anti-wear ability, in enhancing extreme-pressure capacity. The wear scar width can be decreased 0.3mm when the additive in paraffin oil is about 0.25wt.%, when the additive in paraffin oil is about 0.5wt.%, load-carrying capacity can improve 29%. The morphologies, typical element distribution of the worn surfaces were characterized by SEM and EDS, respectively. Its anti-wear mechanism as follows: A permeating layer with rare earth elements was produced in the frictional sub-surface, the layer modified the microstructure and the lubricating state of the frictional surface.
