The effect of triazole (TR), 3-amino-1,2,4-triazole (ATA) and cetyltrimethylammonium bromide (CTAB) on the inhibition of brass corrosion in simulated cooling water system has been studied using electrochemical measurements, scanning electron microscopy (SEM) observations and energy dispersive X-ray (EDX) analysis. The potentiodynamic polarization study reveals that these inhibitors inhibit both cathodic and anodic reactions, indicating a mixed-type control of inhibition and their inhibition depend on the nitrogen number in their structure. It shows that the ATA is the best inhibitor. The interference between CTAB and TR derivatives against corrosion has been also studied. So, a large passive current plate is observed directly from the corrosion potential in the presence of formulation. In addition, the operational parameters effect on the performance of this formulation is also investigated. It shows that its inhibition efficiency increases with pH, immersion time and the presence of corrosion products and takes its performance by increasing in temperature. The SEM/EDX data confirm that the formulation is a corrosion and scale inhibitor.

“…In corrosion tests, the Nyquist plot measured by electrochemical impedance shows a semicircle in the testing media [22], corresponding to the equivalent circuit, as shown in Figure 8, in which Rs represents the electrolyte resistance, Rct is the charge transfer resistance between the electrolyte and electrode, and CPE stands for the double layer capacitance on the electrode surface [23][24][25]. Figure 9, revealing that the charge transfer resistance (Rct) of SPAN deposited on mild steels is several hundred times higher than that of the blank sample (mild steel).…”

Without the addition of inorganic acids, 2,5-Diaminobenzenesulfonic acid (DABSA) molecules form an acid environment, and are then electrochemically copolymerized with AN monomers to generate a self-doped polyaniline (SPAN) film on mild steel substrates. These SPAN deposition films are employed to test the protection efficiency for mild steel in a corrosion environment of HCl and NaCl, respectively. Electrochemical impedance spectroscopy (EIS) and polarization were used to determine the charge transfer resistance (R ct ) and corrosion current (I corr ), respectively. The above two parameters R ct and I corr are combined to evaluate the protection efficiency of SPAN film on mild steel. Experimental results show that the SPAN thin film with the AN/DABSA ratio of 8.8 has the optimal corrosion resistance in 1 M HCl and 1 M NaCl aqueous solutions, respectively.
