Adsorption and corrosion inhibition behaviour of N-(phenylcarbamothioyl)benzamide on mild steel in acidic medium

Inhibition efficiency of aminobenzonitrile compounds on steel surface

“…As seen from figure, Nyquist plots of mild steel is a slightly depressed semicircle and only one time constant is observed in Bode plots. This observation indicates that the corrosion of mild steel in 0.5 M HCl solution is mainly controlled by the rate of charge transfer process [22,23]. The polarization resistance value is directly obtained from Nyquist plot, which includes charge transfer resistance and diffuse layer resistance.…”

N-methyl-2-(2-nitrobenzylidene) hydrazine carbothioamide — A new corrosion inhibitor for mild steel in 1mol·L−1 hydrochloric acid

“…The Randles equivalent circuit used for impedance studies [18] is given in Fig.3(a), where R s is solution resistance, C dl is the double layer capacitance and R ct is the charge transfer resistance. The impedance data obtained from Nyquist plots for the above mentioned systems are given in Tables 5 and 6.…”

Synthesis, Characterization and Electochemical Studies of 4-Methoxybenzoylthiourea Derivatives

“…Thiourea and its derivatives were reported to be the potential corrosion inhibitors as compared with other organic compounds because thiourea molecules contain one S atom and two N atoms [6][7][8]. These atoms act as centre of adsorption that forms a protective layer on the metal surface from the corrosive attack [9][10].…”

“…Corrosion inhibitors are substances that may retard or slow down the corrosion rate when added in small concentration to the system. Organic inhibitors containing nitrogen (N), sulphur (S) and oxygen (O) atoms are considered to be the effective and potential corrosion inhibitors [3][4][5][6]. The inhibitors that have these atoms in their structure may induce greater adsorption of the…”
