    Metals and ceramics exposed to high-temperature salt solutions are susceptible to a form of corrosion caused by fused salts accumulating on unprotected surfaces. This article examines the electrochemistry of such hot corrosion processes, focusing on sodium .   This book is a must for solving high-temperature corrosion problems and learning about corrosion reactions of various high-temperature corrosion modes. Contents: Methods of Testing and Evaluation Oxidation Carburization and Metal Dusting Nitridation Corrosion by Halogen Sulfidation Ash/Salt Deposit Corrosion - Molten Salt Corrosion Molten Metal.

    Both MgCl2-KCl and FLiNaK are being investigated as high temperature heat transfer fluids that could be used in systems for high temperature electrolysis or thermochemical cycles. Initial tests at SRNL have demonstrated the effectiveness of MAX phase coatings applied by PVD at preventing corrosion in molten salts for CSP systems.   Here, we report the design and fabrication of three custom-made apparatus: (i) a multi-port spectroelectrochemical furnace equipped with optical spectroscopic and electrochemical instrumentation, (ii) a high-temperature cell holder for time-resolved optical detection of radiolytic transients in molten salts, and (iii) a miniaturized.

Abstract. Containment materials used in power generating applications are subject to molten salt corrosion. This chapter reviews the data relevant to corrosion. The microstructural evaluation and characterization of stainless steel samples that were tested in molten Li 2 BeF 4 (FLiBe) salt were investigated in this study for evaluating its performance in high-temperature molten fluoride salts.

Recently, stainless steel and FLiBe salt are being actively considered as the main structural alloy and primary coolant of fluoride salt-cooled high. The austenitic stainless steels are high-temperature ferritic steels that can withstand high temperatures while maintaining their strength, this kind of steels are High temperature corrosion in Molten Salts book used as the construction material for solar collectors, hot pipes and the hot salt tank in the two-tank configuration molten salt storage system (Moore et al., ).

High Temperature Molten Salt Corrosion Testing • Identify molten salt/material combinations that have long service life and meet performance needs • Characterize corrosion rates, corrosion mechanisms, and methods to reduce corrosion • Long-term and electrochemical testing • Quartz or Inconel vessels with water cooled flanges.

Hot corrosion of the weldment is the result of the reaction between oxidation and sulfidation, which affects welded joints exposed to combustion gases containing sulfate coal ash at high temperature.

It is also demonstrated that welding processes, weld consumables, temperature of exposure, and mixture of salt environment are important factors in hot corrosion of the weldment. ISBN: OCLC Number: Description: viii, pages: illustrations ; 25 cm.

Contents: Fundamentals of molten salt corrosion --Electrochemistry of corrosion in molten salts --Mechanism of growth, composition and structure of passive films formed on Ni, Fe and their alloys in molten salt electrolytes --Hot corrosion in gas turbines --Fireside corrosion in boilers.

And the corrosion resistance of SS41, 2\frac14Cr-1Mo Steel and SUS strongly depended on the temperature and Cl⁻ content of the molten salt, while Inconel showed high corrosion resistance. High temperature corrosion behaviour of Cr–1Mo, 9Cr–1Mo and SS in molten UCl 3 –LiCl–KCl salt at and °C under inert and reactive atmospheres for 24 h were studied by thermogravimetry.

The results indicate marginal weight gains in all the alloys. Previous studies of high temperature molten salt syst 13 showed that the corrosion rate at the alloy surface is a function of the corrosion environment, ionic diffusi vity in the salt, and. Get this from a library.
