FIELD: metallurgy.
SUBSTANCE: brass-plating of the machined surface of a metal blank is performed in the direction opposite to the direction of subsequent regular microgeometry. When the cold plastic deformation of the blank is done in the same direction as the direction of the brass-plating when feeding a metal plaque lubricant in the deformation zone under pressure.
EFFECT: Bauschinger effect is intensified and the friction force is reduced.
