| Abstract: | The microstructures of the nickel deposit ,which was prepared by pulse-plating technology on uranium surface, have been studied by X-ray diffractometry(XRD),scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results indicate that the crystallographic structure of the deposit is face centered cubic; the deposit has a highly preferred orientation of (200), the relative orientation density of (200) is 3.44; the average grain size is about 45.5nm. The deposit is fine and has multi-grain property as well as some crystallographic defects such as dislocation, stacking and twin. It's feasible to prepare nanocrystalline nickel deposit on uranium surface by pulse plating technology. |
