摘要	In this work, the Ni-Cr nanocomposite films were fabricated with various contents of Cr nanoparticle dispersions and then subsequently aluminized to obtain the Cr nanoparticle-dispersed Ni2Al3 coating at temperature 620 C. For comparison, the samples without Cr nanoparticle dispersions were prepared under the same experimental condition. The results showed that the Ni2Al3 coating with Cr nanoparticle dispersions has a lower oxidation rate than the Cr-free Ni2Al3 coating after oxidation. The result also indicates that Cr nanoparticle dispersions in the Ni2Al3 coating promoted the transformation of 0-into-alpha alumina phase and surface microstructure evolution based on the investigations of photo-stimulated luminescence spectroscopy (PSLS) and scanning electron microscopy (SEM), respectively. Furthermore, with increasing the content of Cr nanoparticle dispersions from 2.5 wt% to 5 wt% in theNi(2)Al(3) coatings can significantly reduce the oxidation rate through accelerated phase transformation of metastable to stable alumina. In addition, the Cr nanoparticles in Ni2Al3 not only mitigate the cavities formation at the interface, but also grow an adherent alumina scale on aluminide.
