FIELD: metallurgy.
SUBSTANCE: method comprises mixing cladding iron powder and aluminium cladding powder and low-frequency thermomechanical processing of the resulting mix. Low-frequency thermomechanical treatment of the mix is carried out at a temperature of 550-600°C in a container with non-oxidizing atmosphere by vertical vessel oscillations with a frequency of 30-50 Hz, amplitude of 7-10 mm for 5-10 min, followed by holding the mixture for 30 s at a temperature of 710-730°C and the indicated vertical oscillations of the container.
EFFECT: provide coating adhesion not lower than the aluminium strength limit.
