A corrosion-inhibiting mixture of compounds has been developed for addition to the water used to rinse metal parts that have been cleaned with aqueous solutions in preparation for adhesive bonding of the metals to rubber and rubberlike materials. Prior to the development of this corrosion inhibitor, the parts (made, variously, of D6AC steel and 7075-T73 aluminum) were rinsed by deionized water,...

We study copper corrosion inhibition by ethanolamine (ETA)with (0, 0.2 ,0.3,0.4,0.5) vol.% concentrations in 100 ppm NaCl solution. This work is carried out by potentiodynamic measurements and Electrochemical Impedance Spectroscopy (EIS). The substrates' surface morphologies are examined by Scanning Electron Microscopy (...

The corrosion inhibition of zinc in 1.0 M H2SO4 solution by Cefuroxime axetil has been studied in relation to the concentration of the additive using weight loss measurement, Linear polarization resistant (LPR) and potentiodynamic polarization (PDP).The results indicate that Cefuroxime axetil inhibited corrosion reaction in the acid medium and inhibition efficiency increased with inhibitor conc...

The effect of potassium iodide (KI) and sodium nitrite (NaNO₂ inhibitor on the corrosion inhibition of mild steel in chloride bicarbonate solution has been studied using electrochemical techniques. Potentiodynamic polarisation data suggest that, when used in combination, KI and NaNO₂ function together to inhibit reactions at both the anode and the cathode, but predominantly anodic. KI/NO₂- conc...

The effect of Mentha spicata L. extract on the corrosion behaviour of carbon steel in 1.0 M HCl solution was investigated using polarization, electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) techniques. The solution containing 250 ppm of the ethanolic solution of extract showed the highest inhibition efficiency (IE). The effect of temperature on the rate of corrosion ...

The inhibition effect of imidazole derivatives 4-methyl-2-propyl-1H-benzimidazole-6-carboxylic acid (MPBI) and 1,4'-Dimethyl-2'-propyl-1H,3'H-2,5'-dibenzimidazole (DPBI) against mild steel corrosion in 1 N HCl solutions were evaluated using conventional weight loss, potentiodynamic polarization, linear polarization and electrochemical impedance spectroscopy. The weight loss results showed that ...

a fundamental study of scale formation of calcium carbonate (caco3) for producing oil wells hasbeen carried out. this article presents the study of the prediction of salt deposition in two differentsynthetic formation waters and investigates the effects of temperature and pressure on calciumcarbonate precipitation. the dependence of the induction period of the precipitation of calciumcarbonate ...

Corrosion inhibition of SAE 1018 steel by Pseudomonas fragi and Escherichia coli biofilms has been evaluated using batch cultures in rich medium (LB) and seawater-mimicking medium (VNSS) at 23 degrees C and 30 degrees C with or without daily medium replenishment. Biofilm components have been stained simultaneously for polysaccharide (calcofluor) and live and dead cells (Live/Dead Baclit viabili...

The inhibiting effect of methionine and tyrosine on the corrosion of iron is researched electrochemically in 0.1M HCl, Quantum chemical calculations were performed. The level of HF with the 6–311G(d,p) basis set for methionine and tyrosine. Corrosion current density has been determined by polarization measures and the inhibition effect was calculated. With an increase in the concentration of in...

The possibility of obtaining corrosion inhibition efficiency from the Scanning Vibrating Electrode Technique (SVET) is investigated. Results are compared with those obtained by Electrochemical Impedance Spectroscopy (EIS) for the inhibition of iron and zinc with cerium nitrate and 1H-benzotriazole. Examples of good and bad estimations are given and an interpretation for the discrepancies observ...
