摘要：

A new kind of organic heterocyclic lubricating additive was prepared and the structure of it was characterized by elementary analysis, FT-IR and13C-NMR spectroscopy. Its tribological behaviour in liquid paraffin were evaluated on the common steel/steel friction pair by the four-ball tester and universal friction & wear testing machine. And the topographies and chemical characteristcs of the worn surfaces were investigated by means of optical microscope, scanning electron microscope and X-ray photoelectron spectroscopy. The results indicated that the prepared lubricating additive could obviously reduce the wear loss of the steel/steel friction pair, enhance the maximum nonseizure load (PB) and improve the anti-wear and friction-reduction properties of the base stock, as might be mainly ascribed to the formation on friction surfaces of the composite boundary lubrication film with ferrous oxide and nitrogen-containing metallic chelate as main components, along with the occurrence of the tribochemical reactions during the rubbing process. © 2020, Politechnica University of Bucharest.
