Abstract

The precise quantification of oxygen concentration in titanium is crucial for various high-performance applications. In this study, we developed reference samples to calibrate high-resolution micro laser-induced breakdown spectroscopy (HR-µLIBS) for oxygen analysis in titanium. Two fabrication methods were employed: (i) oxidation of titanium powder at high temperature in a controlled atmosphere with oxygen, followed by spark plasma sintering (SPS), and (ii) blending titanium powder with TiO₂ powder before sintering by SPS. Homogenized samples were then used to establish a calibration line correlating HR-µLIBS intensity with known oxygen concentrations. To evaluate the HR-µLIBS method, a titanium sample oxidized 500 h at 650 °C in Ar-20 %O₂ was analyzed using both HR-µLIBS and electron probe microanalysis (EPMA). The results demonstrate a strong agreement between the two methods, with HR-µLIBS offering superior speed and improved accuracy at low oxygen concentrations (< 3 at. %).

高分辨率微激光诱导击穿光谱（HR-µLIBS）定量氧用高纯Ti-O基准合金的研制与应用

钛中氧浓度的精确定量对各种高性能应用至关重要。在这项研究中，我们开发了参考样品来校准用于钛中氧分析的高分辨率微激光诱导击穿光谱（HR-µLIBS）。采用两种制备方法：(1)在可控气氛下用氧气高温氧化钛粉，然后进行放电等离子烧结（SPS）；(2)在SPS烧结前将钛粉与TiO2粉混合。然后使用均匀的样品建立HR-µLIBS强度与已知氧浓度相关的校准线。为了评估HR-µLIBS方法，使用HR-µLIBS和电子探针微量分析（EPMA）对钛样品在650°C ar - 20% O2中氧化500 h进行分析。结果表明两种方法之间具有很强的一致性，HR-µLIBS在低氧浓度（< 3 at）下提供了卓越的速度和更高的准确性。%)。
