摘要

The change of corrosion resistance of Q235B steel plate protected by polyurea coating in accelerated corrosion process with scratch was studied by electrochemical test method. Meanwhile, the whole field displacement of Q235B steel plate protected by polyurea coating in 5% (mass fraction) NaCl solution in simulated seawater environment was studied by digital image correlation technology. The results show that when there is a scratch on the surface of Q235B steel plate, the corrosion resistance of Q235B steel plate in seawater solution decreases first and then increases slightly. This phenomenon can also be verified by digital image correlation technology.
