ZID101铸铝合金硅含量较高,用途广泛。作者采用高重复率光源,并用正交设计方法[L_9(3~4)]选择了再现性好、灵敏度高的条件,同时测定ZID101铸铝样品中的铁、锰、镁、铜、锌和高含量硅。 应用—28中型光谱仪,HFI—I型高压火花脉冲发生器。对光源的电容、电感、电阻和辅助间隙距离等放电参数进行了优选,对六种不同条件进行比较,最后确定:电容12mμE;电感100μH;电阻8Ω;辅助间隙1.1mm;每秒放电300次。上电极为φ6mm的石墨电极,顶端车成平面,预燃5s,
ZID101 cast aluminum alloy silicon content is high, a wide range of uses. The author chose the high repetition rate light source and chose the orthogonal design method [L_9 (3 ~ 4)] to select the conditions of good reproducibility and high sensitivity. Meanwhile, the determination of iron, manganese, magnesium, copper, zinc and high in ZID101 cast aluminum samples Content of silicon. Application -28 medium spectrometer, HFI-I high-voltage spark pulse generator. The discharge parameters of the light source such as capacitance, inductance, resistance and auxiliary gap distance are optimized. Six different conditions are compared. Finally, the capacitance is 12mμE, the inductance is 100μH, the resistance is 8Ω, the auxiliary gap is 1.1mm, and the discharge is 300 times per second. The electrode is φ6mm graphite electrode, the top car into a plane, pre-combustion 5s,
