合金工具钢的X射线荧光光谱分析

本文介绍了用X射线荧光光谱仪测量合金工具钢中Mn,Cr,V,W,Ti,Nb,Co,Zr,Ni,Mo,S,P,Si和Cu十四个元素的方法，度样经砂轮抛光酒精棉擦拭后直接测量，结果与内控标样吻合，方法的精密度（n=8)除W，Tr,Nb和Zr外，大多数元素在0．13－9．59％，适应铬钒钢，锰钢，模具钢，中低合金钢等多种钢种的分析。

Analysis of Alloy Tool Steel Using X-ray Fluorescence Spectrometer

This report briefly introduces the analysis of Mn, Cr, V, W, Ti, Nb, Co, Zr, Ni, Mo, S, P, Si and Cu in alloy tool steel with X-ray florescence spectrometer. After being polished with grinding well and being cleaned with ethly alcohol, the test samples can be directly measured, and the results agree well with the standard values of the laboratory standards. The precision of the method (RSD) is in the range of 0.13%-9.56% (n = 8) for all elements except W, Ti, Nb and Zr. The method can be applied to many kinds of steel, such as chrome vanadium steel, manganese steel, die steel, middle-low alloy steel, tool steel. The measure instrument should be rectified with two or three standard samples which the quantity contained is suitable. The standard samples include 1Cr18Ni9Ti, C17Ni2, 25CrMo1V, 30CrMnSiA, 3CrW8V, Gx-8, Cr12MoV, chrome vanadium steel, manganese-boron steel, middle-low alloy steel and other kinds of steel. If there is not conditions to make work curves for all kinds steel separately, sometimes we don't know what kind of steel for one complex sample, the more real way will be to make an overall work curves which contains more kinds of steel as far as possible.
