Abstract

We fabricated a Ni/C composite thick film on ${\alpha}-Al_2O_3$ substrate. A number of precipitations were observed on the film surface. Structural characterization was performed on the observed precipitations using transmission electron microscopy (TEM) with help of the elemental mapping, electron diffraction (ED) and ED simulation. The structural characterization revealed that the precipitation is ${\theta}-Al_2O_3$ having the space group of C2/m (Monoclinic).
