考察了合金元素In含量对Al-Zn-In-Mg-Ti合金组织和电化学性能的影响、并探讨了其在人造海水中的腐蚀行为.结果表明：随着In含量的减少,Al-Zn-In-Mg-Ti合金的组织变得更加均匀,析出相减少,枝晶数量减少,电化学性能也随之改善.当In含量为0.02%时,Al-5Zn-0.02In-1Mg-0.05Ti合金的电流效率达86.3%,实际电容量为2407.3A·h/kg.在人造海水中腐蚀后,Al-5Zn-0.02In-1Mg-0.05Ti合金腐蚀产物易脱落,表面均匀平整.

The effect of In content on microstructure and electrochemical performance of Al-Zn-In-Mg-Ti alloy was investigated and its corrosion behavior in a manmade seawater was also examined.The results show that with the decrease of In content,the alloy became much homogenetie and the amount of precipitates and dendtrites crystals decreases,which then lead to enhancement of its electrochemical properties.The current efficiency and the actual capacitance of the Al-5Zn-0.02In-1Mg-0.05Ti alloy are up to 86.3% and 2407.3A·h/kg,respectively.After corrosion in a manmade seawater for 10 days by a constant current density of 1 mA/cm²,the corrosion products of Al-5Zn-0.02In-1Mg-0.05Ti alloy is easily flaked away and its surface is homogeneous.
