Determining the concentration of material enhancing elements is one of the key issues for ensuring the quality and performance of titanium alloy products. Traditional methods used for determining these elements lack the ability of fast and in situ analysis, and have slowed the research and development of these products. In this work, the determination of yttrium in titanium alloys using laser-induced breakdown spectroscopy assisted with laser-induced fluorescence (LIBS-LIF) has been investigated. With the selective enhancement of the characteristic lines of yttrium under optimized parameters, analytical performance was overwhelmingly improved with a limit of detection (LoD) of 0.3 ppm, a coefficient of determination (R²) of 0.995, and a root mean square error of cross validation (RMSECV) of 12 ppm. The results demonstrate that LIBS-LIF is an effective method for the quantification of yttrium in titanium alloys, and the procedure itself works as a great complement to LIBS based analytical chemistry.

激光诱导击穿光谱-激光诱导荧光法测定钛合金中的钇

确定材料增强元素的浓度是确保钛合金产品质量和性能的关键问题之一。用于确定这些元素的传统方法缺乏快速和原位分析的能力，并且减慢了这些产品的研发。在这项工作中，已经研究了使用激光诱导击穿光谱和激光诱导荧光（LIBS-LIF）辅助测定钛合金中的钇。通过在优化参数下选择性增强钇的特征线，分析性能得到了极大改善，检测限（LoD）为0.3 ppm，测定系数为（R ²）为0.995，交叉验证的均方根误差（RMSECV）为12 ppm。结果表明，LIBS-LIF是定量钛合金中钇的有效方法，该方法本身可作为基于LIBS的分析化学的重要补充。
