摘要：

Corrosion behavior of reinforced bar in concrete was studied by simulating the 4x4 array wire-beam electrode in this paper. These reinforced concretes have been coated respectively in different ways: blank, iron wire with coating resin in surface, concrete with coating resin in surface. By measuring open-circuit potential of iron wire, the impact of different ways of coating were studied on the corrosion of concrete. The result showed that it is the best protection way to coat resin on the surface of concrete, which keep the open-circuit potential within the passivation range all the time, so as to ensure the integrity of the passivation membrane.
