| Abstract: |
| Objective To study the corrosion resistance performance of 3 coating systems (C1, C2, C3) of 30CrMnSiA alloy steel under Xisha marine environment. Method Natural exposure experiments for three coating systems of 30CrMnSiA alloy steel were carried out in Xisha marine environment. The exposure time of experiment was 3 years. Corrosion characteristics and corrosion conditions were tested by measuring the gloss, color difference and electrochemical impedance value. Results The gloss and chromatic aberration of the three coatings decreased gradually with the time increase. The gloss and color difference of the three coatings after exposure were not very different. But the electrochemical impedance values of the three coatings were very different. The impedance value of C1 coating was significantly larger than those of the C2 and C3 coatings. Conclusion C1 coating system has higher corrosion resistance compared with C2 and C3 two coating systems.. |
