摘　　要：用熔融-铸造合金法制备Al-Ga-In-Sn四元与Al-Ga-In-Sn-Zn五元产氢铝合金.研究了用Zn替代部分Ga掺杂及温度对铝合金产氢性能的影响,并通过XRD和SEM分析铝合金的相组成与微观组织.结果表明:随着Zn含量的增加,合金的产氢速率呈现先增大后减小的变化.在Zn的含量达到5%时合金的产氢性能最好,产氢率可达98%.温度对不同样品的影响主要体现在产氢速率与产氢量.合金相和周边铝基体之间的电化学腐蚀促进了合金的水解,反应从合金相周围开始向外扩展.Al-Ga-In-Sn quaternary and Al-Ga-In-Sn-Zn quinary hydrolysable alloys were pre-pared by melting-casting method. The influences on hydrogen production properties of the Zn replacement of Ga and temperature were researched. The phase composition and microstruc-ture of alloys were investigated by XRD and SEM in the study. The results indicated that the hydrolysis speed of alloys with water is firstly increased and then decreased with the increase of Zn contents and when the Zn content is 5%, the hydrolysis properties is the best and the hydrogen production can reach 98%. The main influence of the temperature on samples mainly include hydrolysis rate and output of the hydrogen gas. The electrochemical corrosion between aluminum matrix and alloy phase In3Sn promoted the hydrolysis of alloys,and then the reaction extended along the matrix.
