Corrosion resistance of prestressing steel wires
Cold drawing process is widely used for strengthening of wires made from pearlitic steels for reinforsed concrete structures. Then the steels undergo plastic deformation and the amount of defects rises. It could worsen their corrosion resistance. In this work the effect of cold drawing on the electr...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Cold drawing process is widely used for strengthening of wires made from pearlitic steels for reinforsed concrete structures. Then the steels undergo plastic deformation and the amount of defects rises. It could worsen their corrosion resistance. In this work the effect of cold drawing on the electrochemical behaviour of a pearlitic steel in alkali and neutral environments is investigated. Under passivation conditions in the environment with рН 12.5 the changes in the steel properties are not fixed. The decrease in polarization resistance values and therefore corrosion acceleration as a result of the steel treatment is observed only in the vicinity of corrosion potential in 3% NaCl solution. |
