摘要： An on-line coating adhesion determination apparatus of a galvannealed steel sheet, includes: an X-ray tube which irradiates a galvannealed steel sheet that travels on a transportation line, with X-rays; an optical system which allows the X-rays emitted from the X-ray tube to irradiate the galvannealed steel sheet as a parallel beam and be diffracted; and a detector which measures the intensity of the diffracted X-rays and is installed at a position at which the X-ray diffraction peak corresponding to a crystal lattice spacing d of 1.5 Å or higher is detected, in which an emitted beam luminance of the X-rays is 20 W/mm2 or higher, and the width-direction gain of the X-rays in the optical system is 0.15 or higher. The crystal lattice spacing d may be 1.914 Å. In addition, the energy of the incident X-rays from the X-ray tube may be lower than the excitation energy of Fe-Kα fluorescence X-ray.
