辉光放电发射光谱技术及其在国内钢铁行业中的应用

简单介绍辉光放电发射光谱技术的基础知识及相关书籍情况，重点评述其在国内钢铁行业的应用。国内钢铁行业基体分析涉及中低合金钢、不锈钢、生铁、铸铁、高温合金等；阳极直径4 mm为主，分析元素已达24种，激发功率12～90 W，数据精密度多小于5%；而深度轮廓分析主要涉及镀锌板、镀锡板、彩涂板，氟元素测定和制备电镜样品是其应用的一大亮点。概述辉光放电发射光谱国际标准和国家标准的进展，并对辉光放电发射光谱法、X射线荧光光谱法、电感耦合等离子体原子发射光谱法、火花源原子发射光谱法在低合金钢中多元素测定的重复性和再现性进行比较，数据表明辉光放电原子发射光谱法的重复性值较低，而再现性值偏高。最后对制约辉光放电光谱技术发展的因素进行了探讨。

Glow discharge optical emission spectrometry and its applications in domestic iron and steel industry

The basic knowledge and related books of glow discharge optical emission spectrometry technology were briefly introduced. Its application in domestic steel industry was reviewed in detail. The bulk analysis of domestic steel industry was involved in middle-low alloy steel, stainless steel, pig iron, cast iron and high temperature alloy. The anode diameter was main 4 mm. The analytical elements were up to 24 kinds. The excitation power was 12-90 W. The data precision was mostly less than 5 %. The depth profile analysis was mainly involved in galvanized sheet, tinning sheet and color-coated sheet. The determination of fluorine and preparation of scanning electron microscopy samples were bright spots of its application. The progress of international standard and national standard of glow discharge optical emission spectrometry was summarized. The repeatability and reproducibility of glow discharge optical emission spectrometry, X-ray fluorescence spectrometry, inductively coupled plasma atomic emission spectrometry and spark source atomic emission spectrometry in the determination of multi-elements in middle-low alloy steel were compared. The data indicated that the repeatability of glow discharge optical emission spectrometry was low, while the reproducibility was high. Finally, the factors limiting the development of glow discharge optical emission spectrometry were discussed.
