Abstract：The rapid determination method of Ni, Cr, Mo, P, S, V, Al, Si, Mn, Cu, Ti, Nb, Co, Fe and W in nickel-chromium alloy by X-ray fluorescence spectrometry was established. The spectral overlapping interference among the elements in nickel-chromium alloy was corrected by correction coefficients obtained from binary alloy samples. The absorption and enhancement effect among the elements was corrected by theoretical α coefficient method. The effect of grinding sample with various abrasive belt granularities and materials on the determination was tested. The results showed that, the accuracy of determination results were affected by the granularity of abrasive belt. The found results would be higher when the abrasive belt containing test elements was used. Therefore, the surface treatment conditions of reference materials for preparing calibration curves should be consistent with those of samples. The pollution of abrasive belt materials on test elements should be considered. The proposed method was used for the determination of 15 elements in nickel-chromium alloy. The relative standard deviation (RSD, n=11) of Ni, Cr and Mo was 0.15%, 0.17% and 0.22%, respectively. The precision of other elements was good. The found results were consistent with those obtained by other methods.
