The tribological behavior of nanometer Lanthanum triflate modified with nitrogen-containing organics in liquid paraffin was investigated by a four-ball friction and wear tester, and its tribochemical mechanism was studied by X-ray photoelectron spectroscopy (XPS) Nitrogen lanthanum triflate modified by nitrogenous organic compounds has good extreme pressure, antiwear and antifriction properties in liquid paraffin. Frictional chemical reaction occurs in the process of rubbing, and the physical properties of carbon and nitrogen containing organic compounds Adsorption film, lanthanum oxide, ferrous fluoride, ferroferric oxide and other inorganic chemical reaction film
