Chemical composition and coating weight are important parameters for the characterization of alloy electroplated steel sheets. In X-ray fluorescence analysis of alloy films, fluorescent X-ray intensities are generally the functions of coating weights and contents of alloy films. The X-ray fluorescence analysis using soft X-rays was applied to the analysis of alloy films. Soft X-rays, L series X-rays of the film elements, are absorbed by the plating film higher than K series X-ray. The influence of variation in coating weights on the intensity of L series X-rays is less than on K series X-ray intensity. The results are as follows : (1) It was theoretically and experimentally confirmed that the contents of the alloy films of Fe-Zn and Ni-Zn electroplated steel sheets are analyzed by using L series X-rays, the Zn Lα line, of the alloy element which are not influenced by the variation of coating weights in the normal coating weight range. (2) The intensities of K series X-rays are the functions of coating weights and contents of alloy films. The coating weight is analyzed from both of the K series X-ray intensity and the content determined from L series X-ray intensity by the method of (1).
