“…The observation of the figure reveals that inhibition efficiency and corrosion rate are increasing and decreasing, respectively, with increasing TZs concentration from 200 to 800 mg/L. This is due to the adsorption of TZs molecules over the metal surface and thereby reducing the surface area of the metal sample exposed to the acidic solution . Indeed, the upsurge in inhibition efficiency as the TZs concentration increased from 200 to 800 mg/L can be caused by the result of enhanced surface coverage at higher concentrations through the adsorption of TZs molecules onto the metal surface.…”

The three substituted triazines were synthesized by ultrasound irradiation method and characterized by FTIR, 13 C NMR, and 1 H NMR. The corrosion inhibition behavior of the synthesized inhibitors on N80 steel in 15% HCl was studied using electrochemical analyses and weight loss methods. All three inhibitors exhibited excellent corrosion inhibition performance, and the best inhibition effect was shown by TZ-3 (93.2% at 800 mg/L). EIS measurements suggest that the corrosion inhibition process is a charge transfer controlled. The PDP results indicated that all the triazines are mixed-type inhibitors.Langmuir adsorption model is the best fit among the other tested isotherms.These molecules can act as promising acidizing corrosion inhibitors for the oil gas industry. FTIR, AFM, and UV-vis studies corroborate the adsorption of inhibitor molecules over the metal surface.

“…From Fig. 1, it can be observed that the cathode curves are a linear part, in the form of Tafel lines, indicating that the hydrogen reduction reaction on the steel surface is carried out according to a precise activation mechanism [15]. Table 1 shows that the values of the corrosion current density I corr decrease with the addition of different concentrations of CBE.…”

The inhibition properties of the isopropanol extract of brown seaweed Cystoseira baccata (CBE), against corrosion of carbon steel in HCl 1M medium, was evaluated using the weight-loss method and electrochemical measurements. It was shown that the extract exhibit excellent performance as inhibitors and the inhibition efficiency increased with the concentration. The maximal value of inhibition efficiency is 86.5% obtained by the Tafel method at 700 mg/l at 298 K. The polarization curves indicate that the CBE acts as a mixed-type inhibitor. The results obtained by electrochemical impedance spectroscopy shows that the inhibitory action of this extract is based on the increase in the charge transfer resistance and the decrease in the double layer capacity. The temperature influence studied in the temperature range 298-328 K by weight-loss method shows that the inhibition efficiency decreases with increasing temperature for all concentrations of CBE. The adsorption and activation parameters allow us to suggest the physical adsorption of this inhibitor on the metal. The adsorption of the extract on the carbon steel follows Langmuir adsorption isotherm.

“…Therefore, it is mandatory to find quick, easy, and economical methods of minimizing these adverse corrosion effects on carbon steels [9,10]. Several strategies i.e., inhibitors [1][2][3][4][5][6][7][8]10], materials selection, cathodic protection, coatings [2], and heat-treatment [11], have been reported to control these undesirable mechanisms of degradation.…”

The thermo–mechanical treatments and cyclic annealing processes have the potential of optimizing the corrosion performance of carbon steels in corrosive environments. Herein, an attempt has been made to optimize the corrosion performance of AISI 1345 steel in hydrochloric acid by thermo–mechanical cyclic annealing treatments. AISI 1345 steel was produced and cast in the laboratory and subjected to three types of thermo–mechanical cyclic annealing treatments (TMCA). The first TMCA treatment comprised hot rolling at 1050 °C followed by oil quenching and single austenitizing at 900 °C followed by furnace cooling (TMSA). The second and the third TMCA treatments involved similar hot rolling processes with double austenitizing and furnace cooling (TMDA) and triple austenitizing and furnace cooling (TMTA) processes. Microstructure analysis showed that dual-phase (retained austenite + pearlite) microstructure was achieved after all TMCA treatments with an exception of secondary phase particles precipitation after TMSA treatment. Maximum fractions of retained austenite and minimum fractions of pearlite were achieved after TMTA treatment. Highly refined microstructure of size 26.7 µm was achieved after TMDA treatment whereas; TMSA treatment offered coarse grained microstructure of size 254 µm. Electrochemical analysis was performed in 5 vol% HCl solution using Tafel scan technique. Results revealed that both TMDA and TMTA treatments caused three-fold reduction in corrosion rates (3.025, 2.771 mpy) compared to non-treated steel sample. After 168 h of immersion corrosion analysis in 5 vol% HCl solution, the surface of TMTA treated sample was observed to be partially covered with a very thin, crack-free oxide layer exhibiting minimum oxygen (8.16%) percentage. These features indicated that the TMTA treated sample underwent a very low-intensity minor corrosion attack of HCl solution and exhibited the best immersion corrosion performance among all samples. Electrochemical and immersion corrosion analysis results were in good agreement.
