Transformation of Chemical and Phase Composition in Al/FeAl3(Cr,Ni)/Fe2Al5(Cr,Ni) Laminated Coating at High Temperature Heating

Article Preview

Abstract:

The effect of thermal action at 1100 °C on the kinetics of phase transformations in the coating, obtained by hot-dip aluminizing of 12Cr18Ni10Ti steel, is studied. It was shown that, after 500 h of exposure, the chemical composition is leveled over the entire volume of the sample. Moreover, the predicted retention time of the heat-resistant properties of the coating at 1100 °C is about 2000 h.
