采用X射线荧光光谱法,可实现同时测定C-276合金中Si,Mn,P,Cr,Fe,Mo,W,V,Co,Cu,方法简便快速,便于生产过程控制和产品分析.采用成分相近的17种标准物质建立工作曲线,优化了测量条件并进行谱线重叠校正和元素间的吸收和增强效应的校正,各元素含量与测量强度均能呈现良好的线性关系.用于C-276合金中各元素的测定,具有良好的精密度,测定值与分光光度法、容量法、重量法等标准方法测定结果显示较好的一致性.为建立X射线荧光光谱法测定镍基合金成分提供了思路,为研究X射线荧光光谱分析镍基合金的干扰提供事实依据.“,”The rapid determination method of Si, Mn, P, Cr, Fe, Mo, W, V, Co and Cu in Hastelloy C-276 by X-ray fluorescence spectrometry was proposed, facilitating the production process control and product analysis. The calibration curve was established by the standard materials with similar composition. The spectral overlapping interference and the absorption and enhancement effect were corrected. This method was used for detecting 10 elements in C-276 alloy. The precision was good, and the results were consistent with those obtained by gravimetric, titration and photometric method. The proposed method provided ideals in determination of nickel base alloy by X-ray fluorescence spectrometry, and evidences for interference study.
