In-situ X-ray Diffraction Analysis of Electrodeposition of Zinc Layers by Using Synchrotron Radiation

Abstract

In order to study the dynamic phenomena of electrodeposition of metallic layers, we have newly developed in-situ X-ray diffraction system using an electrochemical cell and an image-plate detector. Electrodepositions of zinc layers on iron (100), (111) single crystals with current densities of 1.0×10³ to 1.0×10⁴ A/m² were demonstrated. It was found that there were two stages for the preferred orientation of zinc layers. It was dominated by the crystallographic orientation of substrate material at the initial stage and the current density (i.e. overvoltage) at the next stage.
