Details of corrosion process of the steel sheet under stress load in the solutions have not been understood well. In this case, it is important to observe the corrosion process in liquid solutions by using nondestructive analytical method. Therefore, we applied a confocal micro-XRF analytical method for this purpose. This method enables a nondestructive elemental imaging near the surface of the materials in the solution. We prepared a sample cell where a Zn plating steel sheet was placed under stress load in NaCl solution. Zn and Fe XRF images were successfully observed in situ for 5 days in two analytical modes: cross sectional XRF imaging and depth-selective XRF imaging.
