Reinforcing steel bar (rebar) is subjected to various levels of strains during service in reinforced concrete (RC) construction. This work aims at understanding the effect of pre-induced plastic strains on the corrosion behavior of a reinforcing steel bar (rebar) by doing electrochemical tests (electrochemical impedance and potentiodynamic polarization) in freely aerated 3.5 pct NaCl solution and cyclic salt-fog test. The interplay between the corrosion products and the corroding tendency of the strained rebars as a function of exposure time is analyzed. The plastic strains have strong effect on the composition of the rusts and polarization resistance of the rusted rebars.

在钢筋混凝土（RC）施工中，钢筋在使用过程中会受到各​​种程度的应变。这项工作旨在通过在自由充气的3.5 pct NaCl溶液中进行电化学测试（电化学阻抗和恒电位极化），并通过循环盐雾测试，来了解预诱导的塑性应变对钢筋（钢筋）的腐蚀行为的影响。分析了腐蚀产物之间的相互作用和应变钢筋的腐蚀趋势随暴露时间的变化。塑性应变对生锈的成分和生锈的钢筋的抗极化性有很大的影响。
