| 英文摘要 | To figure out the microstructure evolution of a Re doped Ni2Al3 coating during vacuum heat treatment, the sample was heated to 1050 degrees C for 2 h and then transformed to Re doped beta-NiAl coating. Re-doped beta-NiAl coating was consisted of four layers including a layer with holes, beta-NiAl and fine dispersed Re, a layer with beta-NiAl and fine dispersed Re, a layer with beta-NiAl and fine dispersed W-rich precipitates and a bottom layer of interdiffusion zone (IDZ). The beta-NiAl type coating was primarily formed by outward diffusion of Ni from the substrate to react with Al of Re doped Ni2Al3 coating. Moreover, the inward diffusion of Al also occurred, thus the formation of holes was attributed to the counter diffusion of vacancies in outer coating. (C) 2021 Elsevier B.V. All rights reserved. |
