文摘

The tribochemical processes in SAE 10W40 engine mineral oil with complexing compound and dioctylphtalate have been studied. A tribofilm that reduces the coefficient of friction is found to be formed on the friction surfaces; it is probed via optical and scanning electron microscopy, FTIR infrared spectroscopy, and X-Ray fluorescence and is established to be composed of copper covering the steel surface and a tribopolymer film. The effect of tribochemical processes with involving the steel surface, copper nanopowder, ligands, coordination compounds, and complex ether in the formation of a tribofilm has also been elucidated.
