采用直读光谱法(OES-Spark)、X射线荧光光谱法(XRF)以及电感耦合等离子体发射光谱法(ICP-OES)测定高合金钢中高含量的元素时,吸收增强效应、晶粒尺寸效应、冶金相组成的不同点、元素间干扰(OES-Spark、XRF)以及较低精密度(ICP-OES)等相关因素都会影响结果的准确性。将样品制备成硼酸盐熔珠后进行检测可以带来很多优势,例如消除相组成和冶金晶粒尺寸效应的影响、对夹杂物(氧化物,氮化物,碳化物)以及任何形状和任何数量的样品进行处理时的高均匀性。本研究开发了一种样品制备的新方法,并将该方法应用于高合金钢标准样品(CRM)的XRF测定中。
When OHS-ICP, XRF and ICP-OES were used to determine the content of high content of high-alloy steel, the absorption enhancement effect, grain size effect , Metallurgical composition differences, OES-Spark (XRF), and lower-precision (ICP-OES) and other related factors can affect the accuracy of the results. Testing samples after they have been prepared as borate beads gives rise to many advantages such as the elimination of phase composition and the effects of metallurgical grain size effects on inclusions (oxides, nitrides, carbides) as well as any shape and any number The high homogeneity of the samples when processed. This study developed a new method for sample preparation and applied the method to the XRF determination of high-alloy steel standard samples (CRM).
