FIELD: metallurgy.
SUBSTANCE: method includes liquid-phase formation of the coating based on nickel aluminide, NiAl3, on the steel parts in aluminium-nickel melt with nickel content 40-45% at 1200-1300°C, at that parts surface is pre-coated with flux based on cryolite.
EFFECT: increased quality of coating, and reduced labour intensity of the coating application process.
