| 1 | Electrochemistry of samarium in lithium-beryllium fluoride salt mixture显示文摘The electrochemical behaviour of samarium was investigated in LiF-BeF2 system on an inert (Mo) electrode by cyclic voltammetry and chronopotentiometry at 804, 833, 847 and 872 K. Redox process Sm3++e-→Sm2+ was recognized and analysed. Cyclic voltammetry data suggested that at potential sweep rates lower than 0.25 V/s, the reduction was limited by the diffusion of Sm3+ ions. It was not possible to observe reduction process of Sm2++2e-→Sm0 due to insufficient electrochemical stability of LiF-BeF2. Diffusion coefficients of Sm3+ ions in LiF-BeF2 were calculated from voltammetric and chronopotentiometric data in the temperature range 804-872 K. Diffusion coefficient values obeyed Arrhenius law. Activation energy was calculated to be 102.5 kJ/mol. | Martin Straka Michal Korenko Frantisek Lisy Lórant Szatmáry | 2011 | Journal of Rare Earths2011，29，8： | 3 |

| 8 | Corrosion and mechanical properties of a novel biomedical WN43magnesium alloy prepared by spark plasma sintering显示文摘Alloying of Mg with rare-earth(RE)elements proved to be beneficial for their in-vitro and in-vivo performance.In this work,a novel WN43(Mg-4 wt%Y-3 wt%Nd)alloy with a well-defined composition was prepared,where,unlike in the commercial WE43 alloy,the possibly harmful RE mischmetal was substituted by less toxic Nd.A modern spark plasma sintering(SPS)technique was used to effectively produce WN43 samples from atomized powders.Sintering temperatures of 400℃-550℃ and holding times of 3 or 10 min were used and wellcompacted final materials were successfully prepared.It was shown that a superior combination of corrosion and mechanical properties was attained in the samples sintered at 500℃ and 550℃,while the effect of sintering time was rather negligible.The performance of this material was exceptional within the group of Mg alloys prepared by powder metallurgy and comparable with conventionally prepared alloys.Moreover,it was shown that a great variety of mechanical and corrosion characteristics can be obtained by altering the SPS parameters so as to fulfill case-specific requirements typical of biomedical materials.Consequently,the novel WN43 alloy prepared by SPS seems to be a particularly suitable material for biomedical use. | Michal Knapek Mária Zemková Adam Gres Eva Jablonská Frantisek Lukác Robert Král Jan Bohlen Peter Minárik | 2021 | Journal of Magnesium and Alloys2021，9，3： | 1 |
