Abstract The inhibition behavior of polyaspartic acid (PASP) as an environment-friendly corrosion inhibitor for WE43 magnesium alloy was investigated in 3.5 wt.% NaCl solution by means for EIS measurement, potentiodynamic polarization curve, and scanning electron microscopy. The results show that PASP can inhibit the corrosion of WE43 magnesium alloy. (PDF) Performance evaluation of poly (methacrylic acid) as The inhibition performance of poly (methacrylic acid) (PMAA) and the effect of addition of iodide ions on the inhibition efficiency for mild steel corrosion in 0.5 M H2SO4 solution were investigated in the temperature range of 303333 K using
Oct 03, 2018 · Qian B, Wang J, Zheng M and Hou B 2013 Synergistic effect of polyaspartic acid and iodide ion on corrosion inhibition of mild steel in H2SO4 Acid Corrosion Inhibition and Adsorption Behaviour of The presence of iodide ions shifts more in the cathodic direction and further decreases the anodic and cathodic reaction kinetics. The mechanism of this synergistic effect has been described in detail in some reports . The iodide ions are strongly chemisorbed on the corroding mild steel surface and facilitate EHEC adsorption by acting as intermediate bridges between the positively charged metal surface and EHEC Materials Free Full-Text Experimental and A novel corrosion and scale inhibitor (TPP) containing tobacco stem extract (TSE), polyepoxysuccinic acid (PESA), and polyaspartic acid (PASP) was obtained by the optimal proportion of the orthogonal test. The anticorrosion effect of TPP for carbon steel was researched by static weight-loss method, on-line simulated dynamic test, electrochemical measurement, and scanning electron microscopy (SEM).
The inhibitor effect of the environmentally friendly corrosion inhibitor polyaspartic acid (PASP) on the corrosion of carbon steel in 0.5 M H2SO4 was investigated by weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and scanning electron microscopy (SEM). Polarization curve results clearly reveal the fact that PASP is a good anode-type inhibitor. Sikachina, A., & Beloglazov, S., (2018). Quantum-chemical Jun 29, 2018 · The article describes the process of amino acid adsorption on iron of mild steel immersed in 0.01 M H2SO4, this process was modeled using HyperChem 8.0.8 and ZINDO/1. This method reflects the protection against corrosion by chemisorption of amino acid on the surface of metal to form a complex adduct, reliably. Synergistic effect of halide ions and gum arabic for the obtained in synergistic manner. The adsorption of GA in combination with iodide ions follows Langmuir adsorption isotherm. GA combined with KI acts as a mixed-type inhibitor in sulfuric acid. KEYWORDS API5L X70 pipeline steel, EIS, gum arabic, iodide ions, sulfuric acid, synergistic effect 1 INTRODUCTION Carbon steel is the most commonly used
FTIR analysis revealed that the synergistic effect due to co-adsorption of iodide ions and PAA is co-operative in nature.
