Qualitative and numerical analysis of chemical composition of selected iron alloys technique wave dispersive spectrometry (WDS) by calibration curves

Purpose: Purpose of the dissertation was accomplish qualitative and quantitative analysis of chemical composition of selected iron alloys using wavelength-dispersive spectroscopy (WDS) by calibration curve method. In this dissertation information about X-ray microanalysis physical basis and about X-ray detection in scanning electron microscope were presented. Design/methodology/approach: Research was execute on scanning electron microscope, on the X-ray diffraction instrument, on energy and wavelength-dispersive spectrometer. Carbon content and confidence interval at unknown steel sample were determined. Findings: Method of calibration curves allowed the designation of the carbon content of the steel samples of unknown chemical composition, depending on a reflection intensities derived from coal. Performed tests have confirmed the possibility of using this method, even in case of depositing the carbon layer. Originality/value: The paper presents qualitative and numerical analysis of chemical composition of selected iron alloys technique wave dispersive spectrometry (WDS) by calibration curves. Carbon content and confidence interval at unknown steel sample were determined.
