| 1 | 冷喷涂铝青铜在海洋环境下抗空蚀方面的研究显示文摘本文研究了用不同热处理制度后Cu Al10Fe5Ni5雾化粉末经冷喷涂所得涂层的相组成、硬度、形貌、结合强度等相关性能,并进行了相关的空蚀性能测试。结果表明:雾化后的Cu Al10Fe5Ni粉末经7小时、600℃的退火后,进行冷喷涂所得到的涂层质量更高,结合强度更好,具有比船用GL-A钢更好的抗气蚀性能。 | S.Krebs F.Grtner T.Klassen 郭东海 | 2015 | 热喷涂技术2015，0，1： | 5 |
| 2 | In vitro biodegradation testing of Mg-alloy EZK400 and manufacturing of implant prototypes using PM(powder metallurgy)methods显示文摘The study is focussing towards Metal Injection Moulding (MIM) of Mg-alloys for biomedical implantapplications. Especially the influence of the sintering processing necessary for the consolidation of thefinished part is in focus of this study. In doing so, the chosen high strength EZK400 Mg-alloy powdermaterial was sintered using different sintering support bottom plate materials to evaluate the possibilityof iron impurity pick up during sintering. It can be shown that iron pick up took place from the steelbottom plate into the specimen. Despite the fact that a separating boron nitrite (BN) barrier layer wasused and the Mg-Fe phase diagram is not predicting any significant solubility to each other. As a result ofthis study a new bottom plate material not harming the sintering and the biodegradation performance ofthe as sintered material, namely a carbon plate material, was found. | M.Wolff M.Luczak J.G.Schaper B.Wiese M.Dahms T.Ebel R.Willumeit-Romer T.Klassen | 2018 | Bioactive Materials2018，3，3： | 1 |
| 3 | Development and experimental validation of kinetic models for the hydrogenation/dehydrogenation of Mg/Al based metal waste for energy storage显示文摘With the increased use of renewable energy sources,the need to store large amounts of energy will become increasingly important in the near future.A cost efficient possibility is to use the reaction of recycled Mg waste with hydrogen as thermo-chemical energy storage.Owing to the high reaction enthalpy,the moderate pressure and appropriate temperature conditions,the broad abundance and the recyclability,the Mg/Al alloy is perfectly suitable for this purpose.As further development of a previous work,in which the performance of recycled Mg/Al waste was presented,a kinetic model for hydro-and dehydrogenation is derived in this study.Temperature and pressure dependencies are determined,as well as the rate limiting step of the reaction.First experiments are carried out in an autoclave with a scaled-up powder mass,which is also used to validate the model by simulating the geometry with the scaled-up experiments at different conditions. | M.Passing C.Pistidda G.Capurso J.Jepsen O.Metz M.Dornheim T.Klassen | 2022 | Journal of Magnesium and Alloys2022，10，10： | 0 |
