| Abstract: | Through cycle immersion corrosion tests,the corrosion resistance of Q345B steel containing a little of RE and normal Q345B steel were compared in the simulated marine atmosphere.Their corrosion rate was compared by the way of weight loss and electrochemical method.The composition of inclusions,corrosive feature and characteristic of rust layer were studied by SEM and XRD.The results indicated that the corrosion rate of Q345B steel containing a little of RE was slower than that of the normal Q345B steel,and ... |
