In this thesis, the advantages and disadvantages of potentiodynamic polarization curve, electrochemical impedance spectroscope and coulostatic method for studying corrosion inhibitors in acidic mediums were compared. And then the effect of three popular acid corrosion inhibitors such as thiourea, dodecylamine and propargyl alcohol on the corrosion inhibition behaviors of Q235 steel in acidic solutions were investigated by these techniques. The anodic desorption behavior and extreme value phenomenon of concentration were surveyed thoroughly as well.
