Schiff base derived from the condensation reaction of analar grade 1-amino-2-naphthol 4-sulphonic acid with cinnamaldehyde was prepared under microwave condition.The Schiff base was analysed by infrared spectroscopy.This Schiff base as a corrosion inhibitor of AZ31 magnesium alloy in 0.05 mol/L HCl solution was studied.The inhibition effect of the Schifif base compound(4Z)-4-(3-phenyl allylidene amino)-3-hydroxy naphthalene-1-sulfonic acid(AC) on AZ31 magnesium alloy corrosion was studied using mass loss,potentiodynamic polarization technique,electrochemical impedance spectroscopy methods.The potentiodynamic polarization curve shows that Schiff base AC inhibits both anodic and cathodic reactions at all concentration,which indicates it is a mixed type inhibitor.EIS results indicate that as the additive concentration is increased,the polarization resistance increases whereas double-layer capacitance decreases.The adsorption of AC on the AZ31 magnesium alloy surface in 0.05 mol/L HCl obeys the Langmuir adsorption isotherm. 展开更多

The corrosion inhibition of mild steel in 1 mol/L HC1 by N, N'-bis (2-hydroxybenzaldehyde)- 1, 3-propandiimine (2-HBP) has been investigated by using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and chronoamperometry measurements. The experimental results suggest that this compound is an excellent corrosion inhibitor for mild steel and the inhibition efficiency increases with the increase in inhibitor concentration. Polarization curves reveal that this organic compound is a mixed type inhibitor. The effect of temperature on the corrosion behavior of mild steel with the addition of the Schiff base was studied in the temperature range from 25 ℃ to 65℃. The experimentally obtained adsorption isotherms follow the Langmuir equation. Activation and thermodynamic adsorption parameters such as Ea, △H, △S,Kads and AG,ds were calculated by the corrosion currents at different temperatures and using the adsorption isotherm. The morphology of mild steel surface in the absence and presence of 2-HBP was examined by atomic force microscope (AFM) images. 展开更多
