DEVELOPMENT OF AN IN-SITU X-RAY-DIFFRACTION SYSTEM FOR OBSERVATION OFELECTRODEPOSITION OF METALLIC LAYERS

In order to study the dynamic phenomena of electrodeposition of metall ic layers, an in situ X-ray diffraction system has been newly develope d using an electrochemical cell and an image-plate detector. Electrode position of Zn on an Fe(100) single-crystal surface with a current den sity at 0.5 A cm(-2) was demonstrated in this study. Time-resolved dif fraction patterns were obtained by scanning the image plate. It was fo und that Zn(101) layers were mainly formed from the initial stage of d eposition and grew continuously on this substrate. Growth of other lay ers, such as Zn(103), Zn(110) and Zn(102), were also detected. On the other hand, Zn(100) and Zn(002) were not observed under this condition .
