Available in PDF, EPUB and Kindle. Book excerpt: The corrosion behavior of an austenitic stainless steel (UNS S30400) has been characterized in a 10,000 hour test conducted in hydrogenated, ammoniated water at 260 C. The corrosion kinetics were observed to follow a parabolic rate dependency, the parabolic rate constant being determined by chemical descaling to be 1.16 mg dm−2 hr−12. X-ray photoelectron spectroscopy, in combination with argon ion milling and target factor analysis, was applied to provide an independent estimate of the rate constant that agreed with the gravimetric result. Based on the distribution of the three oxidized alloying constituents (Fe, Cr, Ni) with respect to depth and elemental state, it was found that: (a) corrosion occurs in a non-selective manner, and (b) the corrosion film consists of two spinel oxide layers--a ferrite-based outer layer (Ni{sub 0.2}Fe{sub 0.8})(Fe{sub 0.95}Cr{sub 0.05})2O4 on top of a chromite-based inner layer (Ni{sub 0.2}Fe{sub 0.8})(Cr{sub 0.7}Fe{sub 0.3})2O4. These compositions agree closely with the solvi phases created by immiscibility in the Fe3O4-FeCr2O4 binary, implying that immiscibility plays an important role in the phase separation process.

Available in PDF, EPUB and Kindle. Book excerpt: Corrosion in nuclear power plants cause reductions in efficiency and increases in deposit build-up on plant surfaces, making for expensive maintentance and potential radiological health hazards. This book guides studies to predict and minimize corrosion, thus making nuclear power safer and more cost effective. Too often, reliance on empirical models and on-site testing of existing plants makes study and prediction of corrosive effects in nuclear reactors into a pricey and lengthy process. Introducing the experimental procedures, set up, sample preparation and computer modeling suggested in this book will save precious time and resources in a field where the significant time and expense to get and keep plants on-line are two of the chief concerns preventing broader commerical viability. - The only book to focus exclusively on preventing nuclear corrosion - Uses computer modelling to tie together chemical engineering, civil engineering, corrosion science, and nuclear engineering into a cohesive solution to a vexing nucelar problem - Includes all fundamental equations, example data sets and experimental techniques

Book excerpt: This two-volume set represents a collection of papers presented at the 18th International Conference on Environmental Degradation of Materials in Nuclear Power Systems – Water Reactors. The purpose of this conference series is to foster an exchange of ideas about problems and their remedies in water-cooled nuclear power plants of today and the future. Contributions cover problems facing nickel-based alloys, stainless steels, pressure vessel and piping steels, zirconium alloys, and other alloys in water environments of relevance. Components covered include pressure boundary components, reactor vessels and internals, steam generators, fuel cladding, irradiated components, fuel storage containers, and balance of plant components and systems.

This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of dissolved oxygen and hydrogen and dilute sulfuric acid in 289°C water on the stress-corrosion-cracking susceptibility of lightly and moderately sensitized Type 304 stainless steel was determined in constant-extension-rate tensile (CERT) tests. The CERT parameters and the fracture surface morphologies were correlated with the concentrations of dissolved oxygen and sulfate, and the electrochemical potentials of platinum and Type 304 stainless steel electrodes in simulated boiling-water reactor (BWR) environments. A particularly high susceptibility to intergranular cracking was found for the steel in the lightly sensitized condition at oxygen concentrations between approx. 0.05 and 0.2 ppM under slightly acidic conditions (pH approx. 6.0 at 25°C), which may, in part, account for the pervasive nature of intergranular cracking in BWR piping systems. Scanning-transmission electron microscopy analyses revealed significant differences between samples in the lightly and the moderately sensitized condition with respect to the width, but not the depth, of the chromium-depleted region at the grain boundaries. The addition of 0.5 ppM hydrogen to the water had only a small mitigating effect on intergranular cracking in water containing oxygen and sulfuric acid at low concentrations; however, oxygen suppression to less than or equal to 0.05 ppM in the reactor-coolant water, by means of hydrogen additions to the feedwater, would be quite beneficial provided impurities are also maintained at very low levels.

This book was released on 2021-12-07 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to provide comprehensive and systematic introduction and summary of corrosion characteristics, mechanisms, and control methods of candidate alloys in sub- and supercritical water environment. First of all, corrosion types of candidate alloys and the effects of major alloying elements on corrosion resistance of potential alloys in sub- and supercritical water are compared and analyzed. At the same time, research status of candidate materials, and development and application trends of several corrosion-resistant alloys are summarized. Then, corrosion characteristics of Ni-Cr, Ni-Cr-Mo, Ni-Fe-Cr and Ni-Fe-Cr-Mo-Cu corrosion-resistant alloys, FeCrAl alloy, and Zircaloy are discussed in detail, including the corrosion rate, the structure and composition of oxide film, and the effects of various surface treatment processes, etc. More specifically, it also investigates corrosion behavior of Ni-based alloy, Fe-Ni-based, and stainless steels in supercritical water. The effects of aggressive species on the corrosion behavior of Ni-base alloys are also explored in supercritical water. Readers will further discover the total corrosion processes and mechanisms of typical candidate alloys in sub- and supercritical water environment. Finally, the work explores the corrosion control methods such as ceramic coatings and passivation processes in supercritical water oxidation and in subcritical water, respectively. Future challenges and development trends of corrosion research of candidate materials in sub- and supercritical water environments are covered at the end of this book. It offers valuable reference for theoretically guiding material selection and design and operating parameter optimization of key equipment in the sub- and supercritical water technologies. The book is written for senior undergraduates, graduate students, scholars, and researchers who are interested in corrosion behavior of candidate materials of supercritical water oxidation system, supercritical water gasification system, and nuclear reactor.

This book was released on 1993 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of 0.02, 1.2 and 2.3 mg/L ozone on the corrosion behavior of 304 stainless steel, Monel 400, and naval brass were studied at room temperature in artificial sea water at pH 7.5, and the results were compared with those obtained for aerated solutions. Corrosion potentials and cyclic polarization curves were measured after 1 and 17 hour exposure times. Instantaneous corrosion rates were measured using linear polarization resistance (LPR) techniques. Long term (30 day) crevice corrosion experiments were also performed on stainless steel and naval brass in aerated and 0.8 mg/L ozonated solutions. Increasingly noble corrosion potentials were observed in the cases of stainless steel and Monel with increasing ozone concentration due to the noble redox potential of ozone. Naval brass, on the other hand, maintained a fairly constant corrosion potential, independent of ozone concentration, due to the formation of a bulk corrosion product on the metal surface. LPR measurements on naval brass reflected the corrosion rates of both zinc and copper due to dezincification occurring on the metal surface. These corrosion rates were found to Corrosion, Stainless steel, Copper nickel alloy, Dissolved ozone, Chloride solutions be independent of ozone concentration and exposure time, although it appears that exposure to 0.02 mg/L ozone after 17 hours resulted in complete dezincification at the surface. The corrosion rate of Monel was found to increase at elevated ozone concentrations, independent of exposure time. Stainless steel, however, showed a decreasing corrosion rate with increasing ozone concentration after one hour due to ozone quickly stabilizing the passive film.
