Application of kelvin Probe to Studies of Fusion Reactor Materials under Irradiation

Plasma Science and technology 2005年第4期7卷 2982-2984页

作者：罗广南 k.yamaguchi t.terai M.Yamawaki Department of Quantum Engineering and Systems Science Graduate School of Engineering The University of Tokyo7-3-1 KongoBunkyo-kuTokyo 113-8656Japan Neutron Science Rearch Center Japan Atomic Energy Research Institute 2-4 ShirakataTokai-muraIbaraki319-1195Japan

Recently, the work function （WF） changes in metallic and ceramic materials to be potentially used in future fusion reactors have been examined by means of kelvin probe （kP）, under He ion irradiation in high energy （MeV） and / or low energy （500 eV） ranges. the results of polycrystalline Ni samples indicate that the 1 MeV beam only induces decrease in the WF within the experimental fluence range; whereas the irradiation of 500 eV beam results in decrease in the WF firstly, then increase till saturation. A dual layer surface model is employed to explain the observed phenomena, together with computer simulation results by SRIM code. Charges buildup on the surface of lithium ceramics has been found to greatly influence the probe output, which can be explained qualitatively using a model concerning an induction electric field due to external field and free charges on the ceramic surface.

Potential Oscillations of a Stainless Steel Electrode during Galvanostatic Polarization in a Mixed Solution of Sulfuric and Chromic Acids

引用

International Journal of Minerals,Metallurgy and Materials 1998年第3期12卷 134-139页

作者： k Ogura W Lou M Nakayama t Fukume(Department of Applied Chemistry, yamaguchi University, Ube 755, Japan Department of Applied Chemistry Yamaguchi University Ube 755 Japan

Potential oscillations of a stainless steel electrode galvanostatically anodized have been observed in amixture of chromic and sulfuric acids. the potential regularly oscillated between 1.6 V vs. SCE (lower) and 2.1V(upper) with a certain frequency. the potential values are affected neither by the composition of chromic and sulfu-ric acids nor by the magnitude of applied current density although the potential frequency is very sensitive to theseparameters. this phenomenon is interpreted in terms of the repeated formation and disappearance of the saturatedlayer of dichromate ions on the electrode surface. Such scheme is consistent with the in situ FtIR spectroscopicresult that the concentration of Cr2O ions on the electrode surface increased with time during the polarization atthe lower potential but the change in concenetion of Cr2O ions was negligible at the higher potential.

Low activation materials have to be developed toward fusion demonstrationreactors. Ferritic steel, vanadium alloy and SiC/SiC composite are candidate materials of the firstwall, vacuum vessel and blanket components, respectively. Although changes of mechanical-thermalproperties owing to neutron irradiation have been investigated so far, there is little data for theplasma material interactions, such as fuel hydrogen retention and erosion. In the present study,deuterium retention and physical sputtering of low activation ferritic steel, F82H, wereinvestigated by using deuterium ion irradiation apparatus. After a ferritic steel sample wasirradiated by 1.7 keV D^+ ions, the weight loss was measured to obtain the physical sputteringyield. the sputtering yield was 0.04, comparable to that of stainless steel. In order to obtain theretained amount of deuterium, technique of thermal desorption spectroscopy (tDS) was employed to theirradiated sample. the retained deuterium desorbed at temperature ranging from 450 k to 700 k, inthe forms of DHO, D_2, D_2O and hydrocarbons. Hence, the deuterium retained can be reduced by bakingwith a relatively low temperature. the fluence dependence of retained amount of deuterium wasmeasured by changing the ion fluence. In the ferritic steel without mechanical polish, the retainedamount was large even when the fluence was low. In such a case, a large amount of deuterium wastrapped in the surface oxide layer containing O and C. When the fluence was large, the thickness ofsurface oxide layer was reduced by the ion sputtering, and then the retained amount in the oxidelayer decreased. In the case of a high fluence, the retained amount of deuterium became comparableto that of ferritic steel with mechanical polish or SS 316 L, and one order of magnitude smallerthan that of graphite. When the ferritic steel is used, it is required to remove the surface oxidelayer for reduction of fuel hydrogen retention. Ferritic steel sample was exposed to the envi

Numerous investigations have led to the consensus that aqueous borate solutions are more complicated than other aqueous inorganic salt *** instance,the polyborate distribution equilibria and their relevant interactions in aqueous borate solution are determined by temperature,pH,boron concentration,counter ions,***,as typical incongruent dissolved compounds,aqueous borate solutions(such as magnesium borate and lithium borate) show some extremely abnormal supersaturated features,which adds to the difficulties for the solid-liquid phase equilibrium prediction and borate mass ***,what’s the chemical substantial for the widely observed and controversial "Salification by diluting" and "Salification by heating" rules? Which is a long pending problem in salt lake *** the present presentation,works we have done in this filed by Raman spectra and calculations(thermodynamic,DFt,CPMD) are retrieved *** attempts from structural aspect with X-ray diffractions and empirical potential structure refinement(EPSR) are ***,some applications based on those results are introduced *** hydration induces ployborate depolymerization or polymerization,which is one of the determining factors for polybrate distribution and seriously affects the solid-liquid phase *** borate brine can crystallize by mixing with some fresh water or diluted brine,which has become one of the key methods for borate mass production from bittern in the salt *** borate anions hydration,ion association is also critical for understanding the supersaturation phenomena of aqueous borate *** such as Li and Mg with tight hydrated sphere,they are difficult in forming direct contact ion pairs(the crystal nucleus for crystallisation).Break the stability of the hydration sphere of those cations by heating or pressurising is a good solution for speeding supersaturated aqueous borate solution crystallisation.
