Abstract

This work aimed to address the limitations of traditional methods in the elemental analysis of magnesium alloys. The femtosecond laser-ablation spark-induced breakdown spectroscopy (fs-LA-SIBS) technique combined with the calibration-free (CF) quantitative analysis method was employed. By optimizing experimental parameters, including discharge capacitance, voltage, resistance, laser single-pulse energy, and delay time, the spectral signal intensity and stability were enhanced. The limits of detection for various elements were determined. Through the CF method, the electron density and plasma temperature were calculated, and the quantitative analysis of multiple elements in standard magnesium alloy samples was carried out. The results showed relative errors within 30 % for most elements (e.g., Al: 3.9 %, Zn: 3.3 %), indicating high precision and stability in the elemental analysis of magnesium alloys.

使用校准-cree飞秒激光烧蚀火花诱导击穿光谱（CF-fs-LA-SIBS）定量分析镁合金元素

这项工作旨在解决传统方法在镁合金元素分析中的局限性。采用飞秒激光烧蚀火花诱导击穿光谱（fs-LA-SIBS）技术结合无标定（CF）定量分析方法。通过优化实验参数，包括放电电容、电压、电阻、激光单脉冲能量和延迟时间，增强了光谱信号的强度和稳定性。测定了各种元素的检出限。通过CF法计算电子密度和等离子体温度，并对标准镁合金样品中多种元素进行定量分析。结果表明，大多数元素（Al: 3.9%, Zn: 3.3%）的相对误差在30%以内，表明镁合金元素分析具有较高的精度和稳定性。
