The Ni-Zn electroplated steel sheet shows good corrosion resistance. On producing this sheet it is important to control the coating weight and the Ni content of alloy film for quality assurance. Online X-ray fluorescence analyzer has been developed for the determination of the coating weight and the Ni content of alloy film. The main features of the instrument are as follows : (1) Analysis can be done full automatically. (2) The X-ray fluorescence method is used. In the analysis system, X-ray intensities are measured by two detectors (ionization chambers), one is with Fe filter and the other with Ni filter. The coating weight and the Ni content are calculated from the intensities measured by the two detectors. (3) This analyzer is running for about two years without any trouble.
