The effect of thermal action at 1100 °C on the kinetics of phase transformations in the coating obtained after aluminizing of 12Kh18N10T steel by immersion in a melt is studied. It was shown that after 500 hours 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 hours.
