Electrochemical corrosion of silicon carbide ceramics / U. Sydow in Materials and corrosion, Vol. 61 N° 8 (Août 2010) 

Public ISBD [article]  in Materials and corrosion > Vol. 61 N° 8 (Août 2010) . - pp. 657–664 Titre : Electrochemical corrosion of silicon carbide ceramics Type de document : texte imprimé Auteurs : U. Sydow, Auteur ; M. Schneider, Auteur ; M. Herrmann, Auteur Année de publication : 2010 Article en page(s) : pp. 657–664 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Corrosion;  silicon  carbide Résumé : Recently, SiC-based ceramics have been found to exhibit corrosion damage patterns, which can only be explained by electrochemical processes. Therefore, the current work focusses on the electrochemical test procedures to determine the corrosion behaviour of solid state sintered silicon carbide (SSiC) ceramics in acidic and alkaline media. The corrosion current densities have been determined from linear voltammetric scans. At anodic polarization potentials, electrochemically induced etching patterns were observed in alkaline solution. The formation of pores and crevices during electrochemical oxidation in acidic solution could be monitored by field emission scanning electron microscopy (FESEM) in addition to transmission electron microscopy (TEM). Impedance spectra measured after anodic polarization could be described by the assumption of a pore model equivalent circuit.

Microstructural investigation of the oxide formed on TP 347H FG during long-term steam oxidation / A. N. Hansson in Materials and corrosion, Vol. 61 N° 8 (Août 2010)

Grumsen, Auteur Année de publication : 2010 Article en page(s) : pp. 665–675 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Austenitic  18–12  stainless  steel;  Cr  diffusion;  internal  oxidation;  steam  oxidation Résumé : The long-term oxidation behaviour of TP347H FG in ultra supercritical steam conditions was assessed by exposing the steel in test superheater loops in a Danish coal-fired power plant and characterising the oxide layer with reflective light and electron microscopy. Double layered oxide scales formed during steam oxidation. TEM investigations reveal that the inner oxide layer consists of particles of metallic Ni/Fe and FeCr spinel in the interior of the former alloy grains and a compact layer of FeCr spinel and Cr2O3 along the former alloy grain boundaries. The morphology suggests that the inner layer grows by internal oxidation of the interior of the alloy grains. The thickness of the inner oxide layer did not change significantly with oxidation time and temperature for exposure times up to 30 000 h. Faster Cr diffusion within the fine-grained alloy at higher temperatures is held responsible for this observation. This hypothesis is supported by kinetic data. The oxide thickness at low and high temperatures after 58 000 h exposure was higher than expected.

Deformation of oxide scales on Fe-20Cr alloy under compressive stress / C. H. Zhou in Materials and corrosion, Vol. 61 N° 8 (Août 2010)

The objective was to understand the effect of mechanical loading on the deformation of oxide scales. It was carried out mainly by comparison of surface morphologies of oxidized specimens observed by scanning electronic microscope (SEM). In all cases, the oxide scales formed on specimens without stress showed a flat surface. However, oxide scales formed on specimens after 20 h of oxidation under a stress of 8 MPa (strain 3.07%) showed slip band characteristics. Furthermore, for longer oxidation time up to 65 h, slip bands formed under a low stress of 2 MPa (strain 1.19%), and grain boundary sliding became the main surface feature for the specimens subjected to a stress of 5 MPa (strain 2.53%). Two typical deformation forms are illustrated in the work.

Pipeline coatings are relatively thick and their evaluations are very time consuming. In this study, experiments on the thick coating samples (roughly 250 and 400 µm) of high solid polyurethane (HSPU) have been conducted to evaluate the effect of high temperature and presence of ions in the media, on the performance of coatings. The experiments were performed in two types of electrolytes, sodium chloride solution (3.5 wt% fraction) and distilled water, at two temperature levels of 25 and 75 °C, respectively. The coating performance was studied using electrochemical spectroscopy impedance (EIS) method. The results of experiments show that the presence of ions reduces the service life of the coating and higher temperature accelerates the degradation process further if oxygen is not limited.

The electrochemical techniques such as potentiodynamic polarization sweep and electrochemical impedance spectroscopy (EIS) were used to disclose the differences of the corrosion mechanisms between both P110 and P110SS steels in CO2-containing solution with various additions of H2S. The EIS data fitted by ZsimpWin software were analyzed and discussed. The experimental results indicated that H2S could accelerate and also inhibit the corrosion attack according to the changes of corrosive environments.

The corrosion rate dependence with immersion time was Δm = atb. Two behaviours for the material surface were evidenced when varying the soil concentration and temperature. Then, the apparent kinetic constant, the soil reaction order and the apparent activation energy were calculated. Analytical and electrochemical characterizations showed that a rough patina layer was build up as a result of the interaction between soil and copper.

Adsorption rate and protective effect of tributyl(cyclohexyl)ammonium chloride inhibitor on the acidic corrosion of steel / A. M. Magerramov in Materials and corrosion, Vol. 61 N° 8 (Août 2010) 

Public ISBD [article]  in Materials and corrosion > Vol. 61 N° 8 (Août 2010) . - pp. 702–708 Titre : Adsorption rate and protective effect of tributyl(cyclohexyl)ammonium chloride inhibitor on the acidic corrosion of steel Type de document : texte imprimé Auteurs : A. M. Magerramov, Auteur ; Z. M. O. Rzayev, Auteur ; I. A. Aliyev, Auteur Année de publication : 2010 Article en page(s) : pp. 702–708 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Acid  corrosion;  corrosion  protection;  inhibition;  steel Résumé : The inhibition of corrosion of a steel surface by an inhibitor, tributyl(cyclohexyl)ammonium chloride (TBCA), was investigated by gravimetric and electrochemical polarization measurements in various aqueous solutions of HCl and H2SO4 acids. It is known that the most extensive corrosive destruction proceeds during the initial stage of contact between the metallic surface and the aggressive surroundings. The change from H2SO4 to HCl considerably decreases the time for formation of an adsorption layer. The high adsorption of the surface-active cationic TBCA on the steel electrode surface can be explained by the specific adsorption of Cl− anions increasing the negative charge on the electrode surface. It was observed that the value of the polarizing current can be increased from time to time by addition of more TBCA inhibitor. This fact can be explained by the low stability of the film-forming layer on the steel. A similar decrease of the protective effect was also observed in HCl solution. The inhibitor provides at least a slowing of the corrosion process (τ = 21 min). It was found that an increase in H2SO4 concentration from 1.0 to 0.2 N did not change the protective action of the inhibitor and had rather high values (θ = 283 ma/h, ψ = 84%, and τ = 14 min at [I] = 3.5 × 10−4 mol/L). It was shown that the attraction constant has a negative value (A = −1.5 and Ka = 22.3) for the inhibitor, which relates to a high value for the adsorption ability of TBCA in HCl solution and therefore with the intermolecular repulsive force between adsorption molecules having similar charges. The protective action of TBCA increases with an increase in temperature, which is correlated with the chemical nature of its adsorption on the steel surface.

For example, 20% of female population and about 6% of male population are allergic to nickel. Therefore, three different textile accessories were tested for metal leaching: the samples were kept at 30 °C in the artificial sweat solution for different time periods and quantified. The results have shown that the limits prescribed by international standards were much exceeded. Samples of such properties present a high risk for human health and should be used with special attention.
