Kinetics Of

Passivation is a common means of material protection against corrosion applied in engineering. It is necessary to study the kinetics of the passive films forming to control the passivation process. A numerical analysis method is proposed and applied to study passivation kinetics of low carbon steel in sodium nitrate solution. Curve of passive film coverage against time is obtained and discussed. A maximum growth rate is found at initiating passive potential during the film forming process, and the film has already begun forming before the initiating passive potential arrived.

The inhibition effects of A-Mo inhibitor on corrosion of carbon steel in 55% LiBr solution were investigated using cyclic potentiodynamic polarization curves EIS experiments, Mott-Schottky analysis, SEM, EDAX and XRD methods. The results revealed that A-Mo inhibitor was capable of inhibiting the corrosion of carbon steel in 55%LiBr solution, exhibiting high inhibition efficiencies around 99.7%. A-Mo inhibitor promoted the formation of a protective passive film composed of Fe, Mo and O elements. The passive film improved the electrochemistry performance and enhanced corrosion resistance of carbon steel.
