Abstract

The alloy layer formation during high-temperature aluminizing at diffusion temperature TD from 1073 to 1273K in air was investigated for austenitic, ferritic and martensitic stainless steels. The void accumulation was observed in FeAl and αFe interface in high-temperature aluminized carbon steel, while in all stainless steels that were not observed. The alloy layers observed in stainless steels at TD=1073K for the diffusion time t=0.6 ks were Fe2Al5 and Al8Cr5. With increasing TD and t, FeAl layer and αFe layer appeared. As TD and t increased further, Fe2Al5 disappeared, and finally become only two layers FeAl and αFe.
