“…The calculated R a values from the height profile diagrams reduced to 26 nm (TZ‐1), 40 nm (TZ‐2), and 6 nm (TZ‐1) as compared to TZs free 127 nm . The reduction of the average roughness values ( R a ) suggests that TZs molecules have adsorbed on the N80 steel surface and reduced the corrosion process . The AFM results are further confirming the order of inhibition efficiency obtained from the weight loss and electrochemical measurement studies.…”

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.

“…In the same medium, excellent results have been obtained by N. K. Gupta et al in their investigation on the corrosion inhibition of carbon steel using expired Atenolol and Nifedipine [15]. Similar results have been obtained by P. Dohare, using expired Tramadol (active substance: tramadol hydrochloride) [16], as well as, A. K. Singh et al using semi synthetic antibiotic Cefdinir [17]. Inhibition efficiencies up to 90 % have been reported by R. S. Abdel Hameed for expired Ranitidine [18].…”

Inhibitors of electrochemical processes have useful applications in corrosion protection of metals and alloys, as well as in galvanotechnics as levellers for the cathodic metal deposition. Active substances of drugs are good inhibitors, taking into account that they have in their molecules structures containing π electrons or lone pair electrons, being able to adsorb on the metal surfaces through weak physical or strong chemical interactions. Significant inhibition efficiency of several drugs have been proved many years ago, but unfortunately, drugs are expensive and their practical applications as corrosion inhibitors for metal and alloys has been delayed. In the present papers, the studies on the inhibition properties in metal corrosion processes of expired drugs have been emphasized, starting with the paper of R. S. Abdel Hameed, published in 2009. There are few studies on the expired drugs used as levellers in the cathodic metal deposition.

“…ads 0 ads (11) It can be found in Table 4 that G Δ ads 0 values of Lys and Arg are both between −20 and −40 kJ•mol −1 , which may reflect that the adsorption of amino acids belongs to a combined type of spontaneous physisorption and chemisorption process. [42] In addition, Arg molecules possess higher K ads and more negative G Δ ads 0 values compared to Lys, generally implying the stronger adsorption on inhibitor/metal interface, which as a matter of fact leads to a more spontaneous adsorption process. [43] Also, the present fact of better inhibition behavior of Arg is in good agreement with the electrochemical measurement results as mentioned earlier.…”

The inhibition effect of amino acids L-lysine (Lys) and L-arginine (Arg), which serve as inhibition films for corrosion of 316L stainless steel in 0.5 M NaCl solution, is studied by electrochemical measurements. The adsorption of the inhibitor molecules on the steel surface is studied by Fourier transformed infrared spectroscopy (FTIR) and surface-enhanced Raman spectroscopy (SERS), accompanied by the characterization of the metal surface by scanning electron microscopy (SEM). All in all, Lys or Arg can obviously restrain the corrosion of 316L steel, while the inhibition efficiency is even higher with the assistance of I − ions. Arg always has better inhibition performance than Lys regardless of the addition of I − ions. FTIR and SERS confirm the adsorption of amino acids on the metal surface; at the same time, the morphology and protection effect of the inhibition films is clearly illustrated via SEM images. Thanks to all experimental measurements as mentioned above and theoretical calculations, a mechanism model is proposed to simulate the corrosion inhibition process of amino acids and the synergistic effect of I − ions on 316L steel.
