Article Preview

High-temperature oxidation resistance of Ni/Al2O3 nano-hybrid materials was described in this paper. Y2O3 doping and SiC co-dispersion in Ni/Al2O3 nano-hybrid materials are useful techniques to improve high-temperature oxidation resistance. On the other hand, nano-Ni/Al2O3 has the crack healing function by high-temperature annealing in air. SiC-Ni/Al2O3 nano-hybrid materials have similar crack healing performance with better oxidation resistance at high temperatures than Ni/Al2O3 nano-hybrid materials.
