| 英文摘要 | Y modified aluminizing coatings were prepared on pure Nb substrates by aluminizing in the pack mixtures with Y2O3 addition. The effects of Y on the microstructure and growth mechanism of the coatings were studied. The results show that the Y has no obvious effect on the phase constitution of the coating and the grain morphology of NbAl3 phase. With the increase in Y2O3 content in the pack mixtures, the Y content on the coating surface increases. After Y modification, the growth mechanism of the coatings is changed from being controlled by the intergranular diffusion of Al atoms to being controlled by the intragranular diffusion of Al atoms; it reduces the growth rate of the coatings and contributes to the formation of two kinds of silk textures (<010>//ND and<110>//ND) in the columnar crystal area of NbAl3 phase. |
