Bulk AlN + Al nanocomposite materials were Synthesized by sintering the compacts of AlN and Al nanoparticles, which were produced by an active plasma-metal reaction method. The sudeces of as-prepared nanocomposite was investigated by X-ray photoelectron spectroscopy (XPS).Results show the surfaces are much degraded and the degradation products are alumina(Al2O3),boehmite(AIOOH), bayerite(AI(OH)3) layer. The mechanism of degradation behaviour in moist environment was also discussed Bulk AlN + Al nanocomposite materials were Synthesized by sintering the compacts of AlN and Al nanoparticles, which were produced by an active plasma-metal reaction method.
