Embodiment Construction
[0028] A method for quantitative fluorescence analysis of cobalt-based alloys, comprising the steps of:
[0029] (1), set the X-ray fluorescence spectrometer, adjust the instrument to adapt to the analysis of cobalt-based alloys, and set the parameters as follows:
[0030] Test equipment: Shimadzu XRF-1800 sequential spectrometer, 40Kw rhodium target.
[0031] Condition setting: the diameter of the mask is 20mm, Cr and elements with larger atomic numbers, the voltage and current are selected as 60kVx55mA, the elements of P and below are selected as 30kVx110Ma, and other measurement parameters are shown in Table 1.
