This book was released on 2019 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stainless steel 304, Nickel, and Inconel 600 were tested for corrosion as working electrodes electrochemically in 0.67Li2CO3-0.33K2CO3 eutectic salt, and 0.3 GDC - 0.7 (0.67Li2CO3-0.33K2CO3) composite salt from 500 to 600 ℗ʻC in the air. The aim of this study was to understand the corrosion mechanism that take place on the electrode surface, and for materials screening in terms of corrosion resistance in both salts. The electrochemical methods employed were Linear polarization resistance (LPR), Tafel analysis, and electrochemical impedance spectroscopy (EIS). The best scan rate of 1mV/s was determined for the LPR and Tafel measurements after conducting a parametric study with different step heights and step times. According to both the LPR and EIS measurements, Stainless steel 304 demonstrated the highest resistance to corrosion in the eutectic salt with high resistance polarization (Rp) and Rct values; which measure charge transfer, and consistent and high P values which measure permeability of the salt through the oxide layer, owing to stainless steel 304 rich Cr content. Inconel 600 performed the second best, possibly due to its chromium content as well. Nickel came in third with low resistance to eutectic salt. In the composite salt, according to the Rp, the icorr and the P values, Nickel ranked exceptionally high possibly due to the formation of a composite nickel oxide cerium gadolinium oxide (NiO-CGO) film on the surface if the nickel electrode. Inconel 600 ranked second, followed by stainless steel. Temperature also played a significant role in contributing to the acceleration of corrosion. As temperature decreased, the resistance of stainless steel 304 to corrosion increase in the eutectic salt. However, for Inconel 600, at higher temperatures resistance to corrosion was high. The corrosion mechanisms based on EIS results using equivalent circuits revealed that the corrosion for the metal structural materials in the salts includes oxide layer formation, and various oxide layers formation with diffusion control and electron transfer.

This book was released on 2012-12-06 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: In spite of considerable efforts over the years to understand and combat materials degradation via corrosion processes, many challenges still remain both in the theoretical understanding of the phenomena and in seeking pratical solutions to the perennial problem. Progress has been slow due to the complexity of the processes and the systems involved. Fortunately, in recent years there has been a renaissance in the development of new electrochemical and optical techniques, as well as advances in instrumentation, which have greatly aided our quest to gain insight into the complex mechanisms involved in metallic corrosion and passivation. Numerous scientific meetings, symposia, and workshops have been held allover the world which attest to the frenzy of activities in corrosion science and technology. However, most of these conferences have dealt mainly with recent research results. There appeared to be a need to assess and disseminate our present state of knowledge in the field as regards measurement techniques, theory, and instrumentation. The present NATO Advanced Study Institute was therefore held in Viana do Castelo, Portugal from July 9 to 21, 1989. The Institute consisted of a series of tutorial lectures, poster sessions, and round-table discussions interspersed evenly over the two-week period. It was attended by 75 participants from several countries representing industry, government and university laboratories.
Download or read book Molten Salts Chemistry written by FREDERIC Lantelme and published by Elsevier. This book was released on 2013-08-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molten salts and fused media provide the key properties and the theory of molten salts, as well as aspects of fused salts chemistry, helping you generate new ideas and applications for fused salts. Molten Salts Chemistry: From Lab to Applications examines how the electrical and thermal properties of molten salts, and generally low vapour pressure are well adapted to high temperature chemistry, enabling fast reaction rates. It also explains how their ability to dissolve many inorganic compounds such as oxides, nitrides, carbides and other salts make molten salts ideal as solvents in electrometallurgy, metal coating, treatment of by-products and energy conversion. This book also reviews newer applications of molten salts including materials for energy storage such as carbon nano-particles for efficient super capacitors, high capacity molten salt batteries and for heat transport and storage in solar plants. In addition, owing to their high thermal stability, they are considered as ideal candidates for the development of safer nuclear reactors and for the treatment of nuclear waste, especially to separate actinides from lanthanides by electrorefining.

This book was released on 2021 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: As some mechanical surface treatments may be applied during service life of nuclear components, the objective of this work is to determine their influence on surface state of the 304L stainless steel (SS) and its oxidation behavior during exposures in a simulated BWR and PWR environment. In this regard, the oxidation features of SS modified surfaces by dry grinding or mechanical polishing were compared. To describe the microstructural modification induced by the surface treatment, subsurface characterizations were first performed. The characterizations tools used are scanning electron microscopy (SEM), transmission electron microscopy (TEM), 3D optical profilometer, and X-ray diffraction. Each surface treatment affects differently the surface state. The underneath surface of the ground specimens presents an ultrafine grain layer and a strong plastic deformation, while the thickness of the ultrafine grain layer is related to the final polishing stage for the polished specimens. Grinding also induces high residual compressive stresses and high roughness compared to polishing. Then, the reactivity of the modified surface was evaluated under different conditions. The electrochemical protocol, based on electrochemical impedance spectroscopy coupled with Mott-Schottky analysis, was firstly set up to study the properties of passive films formed on SS in a borate buffer solution at room temperature as a function of the surface treatment. Then, the reactivity of the surface oxidized in autoclave was determined ex-situ by the same method complemented by morphology and composition characterizations by either SEM, TEM, or X-ray photoelectron spectrometry. Whatever the simulated environment, the mechanical surface treatment mainly influences the thickness and doping density of the inner oxide and the composition and morphologies of the outer oxide precipitates in terms of shape and size. Finally, the impact of the considered environment on oxidation features was also discussed.

This book was released on 2012-12-06 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: When considering the operational performance of stainless steel weldments the most important points to consider are corrosion resistance, weld metal mechanical properties and the integrity ofthe weldedjoint. Mechanical and corrosion resistance properties are greatly influenced by the metallurgical processes that occur during welding or during heat treatment of welded components. This book is aimed, there fore, at providing information on the metallurgical problems that may be encountered during stainless steel welding. In this way we aim to help overcome a certain degree of insecurity that is often encountered in welding shops engaged in the welding of stainless steels and is often the cause of welding problems which may in some instances lead to the premature failure of the welded component. The metallurgical processes that occur during the welding of stainless steel are of a highly intricate nature. The present book focuses in particular on the signif icance of constitution diagrams, on the processes occurring during the solidification of weld metal and on the recrystallization and precipitation phenomena which take place in the area of the welds. There are specific chapters covering the hot cracking resistance during welding and the practical welding of a number of different stainless steel grades. In addition, recommendations are given as to the most suitable procedures to be followed in order to obtain maximum corrosion resistance and mechanical properties from the weldments.
