2×××系铝合金由于加入Zr,使Zn、Ni光电分析时成分超差 ,这样给控制 2 2 19等含Zr元素的铝合金成分带来困难。对 2×××系含Zr铝合金中的Zn、Ni重新制作分析曲线 ,以消除由于Zr的加入对Zn、Ni测定的影响。从而保证其分析精度 ,确保分析数据的准确。
2 ××× Department of aluminum alloy due to the addition of Zr, Zn, Ni ultra-poor photoelectrochemical analysis of components, so to control 2 2 19 and other elements containing aluminum containing Zr elements difficult. Analyze the Zn and Ni in 2 ××× series Zr-containing aluminum alloys to eliminate the influence of Zr addition on the determination of Zn and Ni. To ensure its accuracy, to ensure the accuracy of the analysis of the data.
