FIELD: metallurgical engineering.
SUBSTANCE: method of manufacturing a detail includes the stages of a cold rolling of a substrate (3) using working rolls, the working surface of which has a roughness Ra2.5 less than or equal to 3.6 mcm; applying a metal coating (7) on at least one surface (5) of the annealed substrate (5) by electrolytic deposition to form a metal sheet (1); deformation of a cut metal sheet (1) to form the details, and the outer surface (21) of the metal coating (7) after the deformation stage has a side strain Wa0.8 less than or equal to 0.5 mcm.
EFFECT: increase the corrosion resistance of the detail.
