Research Abstract	In order to fabricate a bulk material composed of nano-sized layers as a new kind of nano-materials, electro-depositing (plating) process is used. An equipment is developed to accumulate more than 100 layers by immersing into different solutions alternately to deposit different metallic layers such as copper and nickel. TEM and SEM are mainly used to investigate the microstructure of samples, and it was found that the layers are coherent each other. Many grain boundaries and twin boundaries are found in the layers, which may cause a fast diffusion of elements.
