FIELD: protection of metals from corrosion. SUBSTANCE: essence of this method resides in shot blasting preliminarily applied coating during period of time which is definable from following inequality: 0,16 ≅ τp2/S≅ 3,6 Hcoat, where τ is coating treatment time in minutes, P stands for air pressure in atmospheres, S denotes area of applied coating, сm2;; and Hcoat represents thickness of applied coating, mm2, at air pressure of 2 to 5 atm. EFFECT: higher resistance to corrosion. 2 cl, 1 tbl
