Research Progress in Seawater Corrosion of Hull Structural Steel

This paper reviews corrosion behaviors of hull structural steel in seawater, and then summarizes effect factors on corrosion resistance of hull steel and relevant methods to improve its corrosion resistance. The paper also summarizes the test methods to investigate and measure the resistance to seawater corrosion of hull steel and further analyzes the suitability of these relevant methods for evaluating the corrosion resistance. Finally, the paper points out the current problems in study on resistance to seawater corrosion of hull steel.
