“…The role of the counter anions (MBr 2 Cl 2 ) −2 in the adsorption of the prepared complex is an important factor, as shown in Scheme 1 . 75 The positively charged carbon steel surface becomes negatively charged through the adsorption of counter anions (MBr 2 Cl 2 ) −2 . Consequently, electrostatic attraction occurs between the positive charge on the two quaternary nitrogen atoms (N + ) and the negative carbon steel surface to form a protective layer on the metal surface where the anions are sandwiched between the positively charged part on the complex and the metal surface.…”

In this work, three nanometal complexes named cetyltrimethyammonium dibromodichloro zincate (CT-Zn), cetyltrimethyammonium dibromodichloro cuprate (CT-Cu), and cetyltrimethyammonium dibromodichloro manganesate (CT-Mn) were prepared, characterized, and evaluated as corrosion inhibitors for carbon steel in water-based mud (WBM). The chemical structure of the prepared complexes was confirmed by the use of Fourier transform infrared spectroscopy, Raman spectroscopy, elemental analysis, atomic absorption spectroscopy, dynamic light scattering, and thermogravimetric analysis techniques. The surface tension of the complexes was measured. The critical micelle concentrations and some of the surface properties were also determined. The compounds were evaluated as corrosion inhibitors for carbon steel in the prepared WBM using potentiodynamic polarization and weight loss methods during the static and dynamic conditions of the drilling operations. The results indicated that the prepared metal complexes showed high anticorrosion action as the inhibition efficiency increased gradually with the increase in the concentrations of the prepared complexes until it reached the maximum value (93.1%) at 300 ppm for CT-Cu. The order of inhibition efficiency of these inhibitors was as follows: CT-Cu > CT-Zn > CT-Mn. The polarization curves showed that these complexes acted as mixed-type inhibitors. According to the results, the adsorption of these compounds obeyed Langmuir adsorption isotherm. Surface analysis of the carbon steel samples was investigated using scanning electron microscopy, energy dispersive X-ray, and X-ray diffraction techniques. Rheological properties, gel strength, thixotropy, and filtration properties were also measured according to American Petroleum Institute specifications.

“…Figure 13a has been illustrated SEM image of polished MS with comparatively smooth surface, MS surface after inundation in 1.0 M HCl solution has been drastically damaged Figure 13b, in the existence of 300 ppm of the Chicoriumintybus extract, surface has been remarkably advanced Figure 13c. This advance in surface morphology is a sign of the protecting layer creation of the Chicoriumintybus extract on the MS surface that one is responsible for inhibition and reduction in the corrosion rate [52].…”

Herein, An examination into the corrosion inhibition of mild steel (MS) in 1.0 M HCl by the Chicoriumintybus extract as a green inhibitor had been achieved via chemical, electrochemical and morphological measurements. The effect of KI additives on corrosion inhibition efficiency was carried out using a weight loss method. The results reveal that the Chicoriumintybus extract inhibited the corrosion reaction by adsorption onto the metal/solution interface. Inhibition efficiency, increased with the Chicoriumintybus concentration and synergistically increased with the presence of KI. The addition of iodide ions to the Chicoriumintybus extract raises inhibition efficiency of 74 to 99%. Polarization data suggest that the Chicoriumintybus extract acts as a mixed inhibition-mechanism. This observation was further corroborated by the fit of experimental adsorption data to the Temkin isotherm. The results were confirmed by AFM, SEM images and ATR-IR for the surface morphology.

“…Tafel curves were obtained using a scan rate of 1 mV s –1 between a potential of −300 and +300 mV. Inhibition efficiency (Tafel %) was evaluated using the following expression 50 50 50 where I corr blank and I corr inh are the corrosion current density values without and with inhibitor, respectively. The experiments were repeated three times to ensure the quality reproducibility of the electrochemical results.…”

Two synthesized polymers were studied as potential corrosion inhibitors for N80 Steel in a sweet corrosive environment. Poly-2-(methacryloyloxy)ethyltrimethyl ammonium chloride (PDMC), or P1, and poly-2-(methacryloyloxy)ethyltrimethyl ammonium chloride- co - N -vinyl-2-pyrrolidone P(DMC- co -NVP), or P2, were investigated using electrochemical impedance spectroscopy, polarization technique, scanning electrochemical microscopy (SECM), scanning Kelvin probe (SKP), and scanning vibrating electrode technique (SVET). The surface was examined using contact angle, scanning electron microscopy, and atomic force microscopy methods. Analyses of electrochemical and polarization techniques revealed a PDMC polymer with a better inhibition efficiency. The SECM, SKP, and SVET methods showed the insulating ability of the polymers that formed a protective coating on the metal surface.
