Paper Title:
Effect of Rare Earth Elements on Corrosion Behavior of Q345B Steel in CSP
  Abstract

The effects of rare earth elements (RE) on corrosion behavior of Q345B steel at marine atmospheric environment in Compact strip production (CSP) technology was studied using alternate immersion test in this paper. The influences of RE on the microstructure, the components of corrosion products, the corrosion dynamic laws as well as the electrochemical properties were also investigated by optical microscope, SEM, XRD, polarization curve and EIS measurements. The results show that the microstructure of Q345B steel in CSP is finer and the corrosion is mitigated due to relatively compact corrosion products with the addition of RE. The corrosion current density of Q345B steel with RE is lower than that of Q345B steel without RE and the corrosion resistance of Q345B in CSP is improved to a certain extent by RE.
