Abstract

Hollow shaped cylinders have been prepared from alumina-nickel composites with a gradient distribution of Ni by centrifugal slip casting method from water based slurries containing Al2O3 and Ni powders, and sintered at 1400°C, in reducing N2/H2 atmosphere. No new phases like nickel aluminate spinel were revealed by X-ray diffraction in the Al2O3-Ni graded composites. Scanning Electron Microscopy (SEM) observations showed the presence of gradient distribution of Ni particles within the cross-section of the samples. Hardness tests confirmed that the nickel particles are distributed in the composite in a gradient way.
