In the article it is considered the mechanism of origin and development of processes of corrosion of armature in
concrete. Determination of conditions of passing electrochemical corrosion of metal allows asserting, that among variety of means of defense of steel in concrete constructions it should be noted measures, directed on creation of dense films on the surface of armature, which provide passivity of metal, prevent access of ions-activators of corrosion. Technologically it can be realized by use of migrant inhibitors of corrosion, by formation on the surface of concrete protective-decorative coating or application of cathode defense of armature at using metals with more subzero potential.
