Abstract

This paper suggests a rapid preparation for quantitative analysis of a type of high-alloyed steel in wavelength dispersive X-ray fluorescence analysis of the allying elements (vanadium, chromium, cobalt, molybdenum, and tungsten). The samples were decomposed with nitric acid and hydrofluoric acid, and then fused with an alkali flux of lithium tetraborate. The synthetic standards for the quantification were prepared by using metal standard solutions of analytes and iron as a matrix component. Analytical results based on the following methods were successfully obtained: a milligram-based calibration with six synthetic standards by using conventional linear calibration curves, and a corrected fundamental parameter calculation with the same synthetic standards. The present method enabled rapid sample preparation and thus simplified an analytical procedure for high-speed steel compared to the conventional wet analysis including inductively coupled plasma atomic emission spectrometry.
