The regularities of formation of the diffusion coatings structure on the surface of the Fe–Cr–Al alloy during hot-dip aluminizing with ultrasonic impact are studied. The phase and chemical compositions of the coatings have been established. It is shown that the ultrasonic impact leads to a change in the intermetallic phase ratio of the coatings without affecting their composition. Exposure to ultrasound promotes the formation of continuous coatings while minimizing the contact duration between the substrate and high-temperature melt.
