A influência do etanol, ácido sulfúrico e cloreto na resistência à corrosão do aço 316L foi investigada por meio de curvas de polarização e medidas de espectroscopia de impedância eletroquímica. No intervalo estudado, o potencial de corrosão do aço foi independente das concentrações de H 2 SO 4 e NaCl em solução aquosa. Por outro lado, em solução contendo 65% (m/m) de etanol e 35% (m/m) de água, os potencias de corrosão foram mais altos do que os observados em solução aquosa. Além disso, o potencial de corrosão do aço foi alterado pela adição de H 2 SO 4 e NaCl em solução. Em soluções com e sem etanol, mais 0,35% (m/m) de NaCl, a presença de 1% (m/m) de H 2 SO 4 inibiu o aparecimento de corrosão puntiforme.The influence of ethanol, sulfuric acid and chloride on the corrosion resistance of 316L stainless steel was investigated by means of polarization curves and electrochemical impedance spectroscopy measurements. Over the studied range, the steel corrosion potential was independent of H 2 SO 4 and NaCl concentrations in aqueous solution. On the other hand, in solution containing 65 wt.% ethanol and 35 wt.% water, the corrosion potentials were higher than those obtained in aqueous solution. Besides, the steel corrosion potential was affected by the addition of H 2 SO 4 and NaCl in solution. In solutions with and without ethanol, plus 0.35 wt.% NaCl, the presence of 1 wt.% H 2 SO 4 inhibited the appearance of pitting corrosion.

“…After the passive oxide film breaking down, the development of corrosion depends on the repassivation kinetics and film structures. A. Kocijan et al reported on the electrochemical behaviour of 316L SS in borate buffer solutions 1) . Here, 316L SS exhibited anodic peaks in cyclic voltammograms at -0.4 V SCE and 0.6 V SCE , indicating the formation of Fe 2 O 3 and the oxidation of Cr(III) to Cr(VI), respectively.…”

The capacity of passive metal to repassivate after film damage determines the development of local corrosion and the resistance to corrosion failures. In this work, the repassivation kinetics of 316L stainless steel (316L SS) was investigated in borate buffer solution (pH 9.1) using a novel abrading electrode technique. The repassivation kinetics was analyzed in terms of the current density flowing from freshly bare 316L SS surface as measured by a potentiostatic method. During the early phase of decay (t < 2 s), according to the Avrami kinetics-based film growth model, the transient current was separated into anodic dissolution (i diss ) and film formation (i film ) components and analyzed individually. The film reformation rate and thickness were compared according to applied potential. Anodic dissolution initially dominated the repassivation for a short time, and the amount of dissolution increased with increasing applied potential in the passive region. Film growth at higher potentials occurred more rapidly compared to at lower potentials. Increasing the applied potential from 0 V SCE to 0.8 V SCE resulted in a thicker passive film (0.12 to 0.52 nm). If the oxide monolayer covered the entire bare surface (θ=1), the electric field strength through the thin passive film reached 1.6 × 10 7 V/cm.

Poly(indole-5-carboxylic acid) (PICA) has been synthesized by electrochemical polymerization technique from different concentration of poly(indole-5-carboxylic acid) using lithium per chloride as oxidation agent at different scan rate. The as-synthesized PICA was characterized using Fourier transform infrared spectroscopy (FT-IR) and Proton nuclear magnetic resonance spectroscopy ( 1 H-NMR). Thermal analysis of the PICA was performed by Thermo gravimetric analysis (TGA). The corrosion protection performance of low nickel stainless steel (LN SS) specimens coated with 0.1 M concentration of PICA was investigated in 0.5 M H 2 SO 4 medium using potentiodynamic polarization and electrochemical impedance spectroscopic (EIS) methods. The morphological properties of the polymer were characterized by scanning electron microscopy (SEM). The as-synthesized PICA has been used in order to achieve adherent, as well as environmentally preferential good anti-corrosive coating. Electrochemical corrosion tests and surface analysis results evidently showed that PICA coating served as a stable mass matrix on LN SS against corrosion. It was also revealed that the coating of PICA at 0.1V scan rate with 0.1M indole-5-carboxylic acid exhibited the best corrosion resistance among all concentrations.
