该文通过辉光放电质谱法(GDMS)对3种不同粒度段FGH96高温合金粉末中14种关键痕量元素的相对灵敏度因子(RSF)进行了系统分析,并首次将不对称电荷转移(ACT)理论应用于镍基高温合金中Mg元素的RSF系数校正。实验结果显示,B、P、S等13种痕量元素的RSF系数基本不受粉末样品粒度影响,可以使用块状标准物质对其RSF进行修正。通过对不同Mg含量梯度的样品进行考察,对Mg元素的RSF系数提出了校准方案。考虑到基体元素Ni对Mg元素的影响,在准确度要求较高时应根据实际Mg含量高低及粒度段范围建立两套RSF系数进行修正。同时给出了两套RSF系数的参考值,对Mg含量3 μg/g平均粒度200目的样品及30~300 μg/g平均粒度-80~+120目的样品相应的RSF参考值分别为1.16和0.41。
In this paper,the relative sensitivity factor(RSF) of 14 key trace elements with three different particle size ranges of FGH96 superalloy powder were systematically analyzed by glow discharge mass spectrometry(GDMS),and the asymmetric charge transfer(ACT) theory was applied to the RSF coefficient correction problem of Mg element in nickel-based superalloys for the first time. The experimental results show that the RSF coefficients of 13 trace elements such as B,P,and S are basically not affected by the particle size of powder samples,and their RSF can be corrected by bulk standard materials. Through the investigation of samples with different Mg content gradients,a new calibration scheme was proposed for the RSF coefficient of Mg element. Considering the ACT influence of matrix element Ni on Mg element,two sets of RSF coefficients should be established according to the actual Mg content and particle size range for correction when the accuracy requirement is high. This paper gives the reference values of two sets of RSF coefficients. The corresponding RSF reference values for samples with Mg content of 3 μg/g and average particle size of 200 mesh and samples with Mg content of 30-300 μg/g and average particle size of -80~+120 mesh are 1.16 and 0.41,respectively.
