不锈钢特殊零件中镍、铬、锰、钼、钴和钛的X射线荧光光谱无损分析周建兰(洛阳船舶材料研究所) X射线荧光光谱法可以满足快速无损同时测定多元素含量的要求。为减少误关来源,要有相应的固体标样。並保持试样表面X射线辐照面积一致。为此,选用三个以上的基体相同或成分相近的固体标样,绘制荧光强度-浓度关系曲线。然后根据相同条件下测得的试样中待测元素的特征X射线荧光强度,直接从该曲线上查出相应的浓度。在曲线线性部分的范围内可得到准确结果,此时,加只有一个标样,只要牌号相 Nondestructive Analysis of Nickel, Chromium, Manganese, Molybdenum, Cobalt and Titanium in Stainless Steel Special Parts by X-Ray Fluorescence Spectrometry ZHOU Jianlan (Luoyang Institute of Marine Materials) X-ray fluorescence spectrometry can satisfy the requirement of rapid and nondestructive determination of multi-element content. To reduce the source of false positives, there should be a corresponding solid standard sample. And maintain the sample surface X-ray irradiation area. To this end, the choice of more than three of the same matrix or similar solid standard sample, draw fluorescence intensity - concentration curve. Then according to the same conditions measured under test elements in the characteristic X-ray fluorescence intensity, the corresponding concentration found directly from the curve. In the linear part of the curve can get accurate results, at this time, plus only a standard sample, as long as the brand phase
