摘      要：The fractional free volumes(FFVs)of the adsorption films formed with different ratios of dipropargyl methoxythiourea imidazoline(DPFTAI)and pyridine quaternary ammonium salt(16BD)were calculated by simulation to determine their synergistic corrosion inhibition *** results suggest that the composite corrosion inhibitor at the molar ratio between DPFTAI and 16BD of 4:1 gives the best corrosion inhibition *** simulation method to predict the synergistic effect between corrosion inhibitors was further validated by mass loss and electrochemical *** finding delivers valuable understandings of inhibition mechanism of corrosion inhibitors.
