The impedance plot for N80 carbon steel in 3% NaCl
solutions in the absence and presence of 2M2 at pH 4 and
25°C is illustrated as Nyquist plots in Fig.2.All the EIS
plots have a depressed semicircle at high frequencies with
center under the real axis,which is the characteristic for
solid electrodes and has been attributed to roughness and
other inhomogeneties of the electrode [32,33].The highfrequency
capacitive loop is attributed to the double layer
capacity in parallel with the charge-transfer resistance (Rct).
Though it is probably a composite value representing
dissolution of the iron and other alloying elements,it is
governed by the dissolution of iron since iron is the major
component of the alloy and iron is a highly active metal in
acidic media [34].
In the absence of the inhibitor (Fig.2 inset),the
impedance spectrum is characterized by a low-frequency
inductive loop.The inductive loop is ascribed to the
adsorption of species exhibiting negative change in the
surface coverage with potential [34,35] on the surface of
the metal.As the 2M2 is added into the system,the
inductive loop is transformed into an oblique line (of about
45°) at the low frequency; a typical feature of Warburg
impedance.The Warburg impedance is an indication of
diffusion control as species transfer through surface film or
mass transport through the electrolyte.A closer look at the
curves also shows an indication of a capacitive loop at low
frequency in the presence of 2M2.
