CeO2 nanoparticles were co-electrodeposited into an alumina-forming Ni-Al nanocomposite that was composed of nanocrystalline Ni matrix and dispersed Al nanoparticles. Cyclic oxidation in air at 1000 degrees C for 126 h showed that the alumina-forming nanocomposite scaled faster than its counterpart which contained a CeO2 addition, due to the formation of numerous surface NiO nodules and internal oxidation of aluminum as a result of the composite intergranular cracking during the cycling. The intergranular cracking was profoundly prevented when the CeO2 was present. (c) 2006 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
