Outline of Final Research Achievements

The process to fabricate nano-rod array on Ni grains via aluminizing and internal oxidation and chemical polishing was developed. It is described that nano-rod array covered with nano-Ni parcels via reduction in NiAl2O4 nano-rods should be prepared by applying this process. However, continuous internal precipitates were formed in cases of usage in Ni grains. As ar result, surface of Ni grains with nano-rod array is partially obtained on the Ni grains. It is necessary to optimize aluminizing and oxidation conditions to fabricate nano-rod array surface on the Ni grains.
