研制了含有少量Zn、Bi、Te、In、Gu、Pb和Ti之中单个元素或多种元素的铝合金,它们有可能用于碱性铝-空气电池中作为燃料来使用.合金化元素含量<1%的二元合金,在50℃的4MKOH溶液中显示出的腐蚀速率比纯铝在同样介质中的腐蚀速率要高.添加两种或更多种合金化元素时,在开路中的腐蚀速率急剧降低到比纯铝的还低很多.已确认一些含Ga、In、Ti和P的铝合金有希望作为高性能的燃料.已发现压力加工(冷加工)对腐蚀速率几乎没有可再现的影响,但是Al-O.5%Ga合金除外,这个合金在最小加工量为50%的冷加工后可显示出不同的腐蚀速率.腐蚀速率数据还表明,含很少量的合金化元素就足以能提高合金的抗腐蚀性能,而含量超过临界值后,几乎不改善合金的抗腐蚀性能.
Aluminum alloys containing a small amount of single or multiple elements of Zn, Bi, Te, In, Gu, Pb and Ti have been developed and may be used as fuel in alkaline aluminum-air batteries. Alloying elements <1% binary alloy shows a higher corrosion rate in 4M KOH solution at 50 ° C than pure aluminum in the same medium.When two or more alloying elements are added, corrosion in open circuit The rate has been drastically reduced to a much lower extent than pure aluminum.It has been confirmed that some aluminum alloys containing Ga, In, Ti and P are promising as high performance fuels.It has been found that press working (cold working) has almost no reproducible effect on the corrosion rate , Except for the Al-0.5% Ga alloy, which shows a different corrosion rate after cold working at a minimum of 50%. The corrosion rate data also shows that a very small amount of alloying element is sufficient Alloy corrosion resistance, and content exceeds the critical value, almost no improvement in the corrosion resistance of the alloy.
