摘要
提出了直读光谱法测定高碳铬镍合金钢中碳、硅、锰、磷、硫、铬、镍、铜、钼、钒、钛、铌等12种元素的含量。优化的试验条件如下:① 吹氩时间为4 s;② 预积分时间为6 s;③ 积分时间为5 s。12种元素均在一定的质量分数范围内与其光谱强度呈线性关系。方法应用于标准样品(11X-15310)的定值分析,测定值的相对标准偏差(n=11)在0.17%~4.2%之间。应用此方法分析了3种标准样品(95-021-4、C1290和YSBC11017-2003),测定值与认定值相符。
A method of direct reading spectrometry for the determination of 12 elements, i.e. C, Si, Mn, P, S, Cr, Ni, Cu, Mo, V, Ti and Nb in high carbon Cr-Ni alloy steel was proposed. The optimized conditions found were as follows: ① argon-blowing time: 4 s; ② pre-integration time: 6 s; and ③ integration time: 5 s. Linear relationships between values of spectral intensity and mass fraction of the 12 elements were kept in definite ranges. The proposed method was applied to the certification analysis of a standard sample (11X-15310) with RSD′s (n=11) in the range of 0.17%-4.2%. The proposed method was used in the analysis of 3 standard samples (95-021-4, C1290 and YSBC11017-2003), giving results in consistency with the certified values.
