“…Moreover, in the presence of inhibitors C1, C2, and C3, n is found to be between 0.72 and 0.79, and these values are lower than those obtained in a blank solution (0.87). This is due to an increase in surface inhomogeneity as a result of inhibitor adsorption …”

“…The corrosion potential ( E corr ) and current density ( i corr ) were determined by extrapolating data from Tafel curves. The inhibition efficiency (IE p , in %) was determined using eq I E p 0.25em ( % ) = i corr − i corr ( inh ) i corr × 100 where i corr(inh) and i corr are the corrosion current densities with an inhibitor and without an inhibitor, respectively.…”

The inhibitory activity of three prepared azo compounds derived from Schiff bases, namely, bis[5-(phenylazo)-2-hydroxybenzaldehyde]-4,4′-diaminophenylmethane (C1), bis[5-(4-methylphenylazo)-2-hydroxybenzaldehyde]-4,4′-diaminophenylmethane (C2), and bis[5-(4-bromophenylazo)-2-hydroxybenzaldehyde]-4,4′-diaminophenylmethane (C3), against corrosion of steel type XC70 in (HCl, 1 M DMSO) medium was investigated experimentally by electrochemical measurements and theoretically using density functional theory (DFT). The correlation between corrosion inhibition and concentration is direct. The maximum inhibition efficiency at 6 × 10–5 M for the three azo compounds derived from Schiff bases was 64.37, 87.27, and 55.47% for C1, C2, and C3, respectively. The Tafel curves indicate that the inhibitors follow a mixed but predominantly anodic inhibitor system and have a Langmuir isothermal adsorption process. The observed inhibitory behavior of compounds was supported by DFT calculation. It was also found that there was a strong correspondence between the theoretical and experimental results.

“…EIS showed a decrease in the values of double-layer capacitance and an increase in the value of the charge transfer resistance with increased concentration of sodium metamizole. Schiff (1Z)-N-[2-(methylthio) phenyl]-2-oxopropane hydrazonoyl chloride (S1) showed anticorrosive property for mild steel in 1 M HCl [38]. Corrosion inhibition efficiency of S1 increased with increasing concentration of inhibitor and decreased with increase in temperature from 25° to 55°C.…”

Metal corrosion constitutes degradation of metals in the presence of favorable corrosive atmosphere. It worsens metal quality. The prevention of metal corrosion is so significant to save metals for their better utility. Corrosion inhibitors are widely used for the mitigation of metal corrosion. Small organic molecules as corrosion inhibitors are showed prominent corrosion inhibitive property because of their unique electron donating capacity to the metal orbitals. The bonding occurred between organic molecules and metals are main aspect to retard the corrosive environment toward metal.
