Chemical Reaction of In-situ Processing of NiAl/Al2O3 Composite by Using Thermite Reaction
摘要
NiAl / Al2O3 composite were synthesized by thermite reaction of nickel oxide and aluminum powder mixtures. The phase, the microstructure of the composite, as well as the thermite reaction mechanism, were investigated by X-ray diffractometry ( XRD ), scanning electron microscopy (SEM) combined with differential scanning calorimetry ( DSC). The experimental results show that the thermite reaction leads to the interpenetrating network structure of NiAl/Al2O3 at 1223K for 60min and the chemical reaction apparent activation energy is Eap = 166.960± 13.496 kJ· mol-1 in the NiO/Al system.
