Abstract:

Four fine chemicals were designed, synthesized, characterized, and used as multifunctional lubricant additives. Their thermal stability were investigated, and their oil solubility and corrosion resistance in liquid paraffin (LP) were studied. The tribological performances of four additives were systematically evaluated with a four-ball machine. The surfaces morphology and elementary composition of the worn scar was recorded and analyzed by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS), and the reaction mechanism was initially discussed. It was found that the four additives exhibit high thermal stability, good oil solubility and excellent corrosion resistance. Four additives could obviously improve the extreme pressure performance, wear resistance performance and anti-friction performance of LP. The additives were involved in the tribochemical reaction, and a complex reaction film was formed during the friction process.
