The

Nyquist plot was observed to evaluate the pattern to the conditions of reinforced concrete sample under wet and dry condition.

d1]) were determined from

Nyquist plot by fitting the data using Boukamp software.

Moreover, the potential problems with proper frequency gridding can be overcome using

Nyquist plot based approach from (Soylemez et al.

From the

Nyquist plot, the impedance can be represented as a vector of length [absolute value of Z].

Each time constant from the equivalent circuit appears as either a semicircle in a

Nyquist plot or a peak in the phase angle in a Bode plot.

In fact, the

Nyquist plot has great similarity with the well known Cole-Cole plot used to define dielectric characteristics of materials.

The degradation steps are described below and shown in Figure 3 with (1) an example of the appropriate equivalent circuit with typical values for the electrical elements, (2) a Bode plot, and (3) a

Nyquist plot.

Nyquist plotA

Nyquist plot provides information on the diffusion process occurring in the coating system.

The existence of a single semicircle in

Nyquist plot shows that there was only single charge transfer process during the anodic dissolution of MS and remained unaffected in the presence of N-Benzylimidazole added in the acid.

Furthermore, this technique can be embellished with the

Nyquist plot based approach from (Soylemez et al.

When the impedance is measured at a number of frequencies and is plotted on the Cartesian axes, the resulting plot is called a

Nyquist plot.
