As a result,when we added the Ce of mass fraction of 1% of in the process of hot-dip,it would accelerate the formation of the phase of Fe4Al3Ce and Fe2Al5 out of coating and repress the growth of the phase of Fe2Al5 in the inner.At 1000 ℃ / 4h in the process of the diffusion ,Ce facilitated the transformation from γ to the phase of α and the precipitation of the phase of α from Ni3Al phase,then there are the phase of Ce-rich generating in the inner penetrative layer.At 800℃/360h in the oxidized process,Ce accelerated the formation of the phase of slight Fe4Al3Ce and Fe2Al5 out of penetrative layer and made the outer layer of densely penetrative layer homogeneously.At 1000℃/360h in the oxidized process,Ce accelerated the growth of the phase of α so that there are massive phase of σ in the penetrative layer. In the oxidized process, rare earth Ce was able to raise the inoxidizability of the penetrative layer at high temperatures of 800℃ and 1000℃. |
