摘要

利用电子背散射衍射(EBSD)技术及快车速电子铝箔腐蚀工艺，研究了单级退火温度425、450、475、500℃(保温时间为15 h)对电子铝箔再结晶立方织构及后续腐蚀性能的影响。结果表明，4种退火工艺下，电子铝箔的再结晶织构几乎全部为立方织构。随着退火温度升高，铝箔的平均晶粒尺寸、氧化膜厚度逐渐增加；退火温度为450℃时，对应腐蚀箔性能达到最优，其中比电容为0.773μF/cm~2

折弯次数为56次，质量损失率为30.82%。

Abstract

The effects of single stage annealing temperature at 425

450

475

500 ℃ for 15 h on recrystallized cube texture and subsequent corrosion performance of electronic aluminum foil were investigated by EBSD technology and fast-speed electronic aluminum foil corrosion process. The results indicate that recrystallized texture of electronic aluminum foil is almost cube texture under all annealing processes.With the increase of annealing temperature

the average grain size and oxide film thickness of aluminum foil is increased gradually. When the annealing temperature is 450 ℃

the performance of corrosion foil is desirable

where the specific capacitance is 0.773 μF/cm~2

the number of bend is 56 cycles

and the weight loss rate is 30.82%.
