FIELD: metallurgy.
SUBSTANCE: steel sheet contains at least one layer of zinc. Said layer is applied by means of vapour-jet deposition at a sonic speed by means of ejection chamber. The ratio between the Pc pressure inside the coating chamber and Pe pressure inside the chamber for ejection of zinc is 2⋅10-3-5.5⋅10-2. According to the second version, the Pc pressure maintained within the chamber for the application of coating is 6⋅10-2-2⋅10-1 millibar.
EFFECT: improved sheet properties.
