摘要/Abstract

摘要： 为了降低铝水反应的启动温度,提高铝基燃料的反应速率,通过熔炼法制得一种新型铝基合金。采用原子发射光谱(AES)、差热分析(DTA)和水解性能测试考察了制备方法、合金表面形态、反应温度和两种不同添加剂对合金性能的影响,并且考察了合金作为阳极材料的性能。结果表明:合金常温与水反应速率为35.53mL/(g·min),反应率为82.1%。球磨改变合金表面形态之后,不但反应速率提高10倍,反应率也得提高到90.52%。对体系预热能有效的降低反应启动时间,同时提高反应率也提高到92.69%。自行设计的熔炼装置能使金属镁的烧损率降低到3%。添加剂b的综合性能优于a,能使合金的熔化温度大幅降低为855K。作为电池阳极时,由于自腐蚀析氢比较严重,放电性能不稳定,需进一步优化降低自腐蚀。 

Abstract: In order to reduce the startup temperature and increase the reactivity of Al-based composites, the new Al-based alloy was obtained via melting casting.The effects of preparing method,particle size, temperature and two different additives on their properties were studied through the measurments of Atomic Emission Spectroscopy(AES), Differential Thermal Analysis(DTA) and hydrolysis. The performance of alloy as battery anode was investigated and the results show that at room temperature, the reaction rate of Al-based alloy is 35.53mL/(g·min) and the reactivity is 82.1%. However, the reaction rate increases over 10times after milling and the reactivity also increases to 90.52%. Heating reactor can reduce its startup time and promote the reactivity to 92.69%. Using the device self-designed can decrease the burn-off rate of Mg to 3%. The additive b is better than a and results in the descent of the melting point of Al-based alloy to 855K. As battery anode, the performance of alloy is not stable due to hydrogen-evolution self-corrosion of alloy and need to be optimized. 
