摘　　要：12.5 mm厚的6R01T4铝合金手机背板材料进行晶粒度检测时,使用常用的化学浸蚀剂或阳极化覆膜方法制备的样品,再结晶的晶粒显现不完全,在检测时出现漏点的现象,得出的数据误差较大。通过反复试验研究,使用HF、HCL、H_(2)O的体积比为1∶1∶11的浸蚀剂浸蚀210 s,再经阳极化覆膜后,制备出的样品能较完全显现晶粒,可保证晶粒度检测结果的准确性。The grain size testing was conducted on the 12.5 mm thick 6R01T4 aluminum alloy used for the 12.5 mm-mobile phone backboard.When using common chemical etchants or anodized coating methods to prepare samples,the recrystallized grains did not show completely,and there were missing points during testing,resulting in significant data errors.Through repeated experimental research,the article concludes that after etching with HF,HCL,H_(2)O as 1:1:11(by volume)for 210 seconds,and then anodizing and coating,the prepared sample can fully display grains,ensuring the accuracy of grain size detection results.
