It has been experimentally proven that the effect of ultrasound on the melt during hot-dip aluminizing does not affect the phase composition of the diffusion zone formed as a result of heterogeneous reactions at the interface between aluminum and iron-based alloys. It is shown that at a fixed temperature, the frequency of supplied acoustic vibrations of 18-20 kHz and an amplitude of 10-15 μm, the thickness of the coating and diffusion zone decreases by 30-50 %.
