Abstract

This paper studies the corrosion control and protection technologies of underwater steel structures, in order to prevent corrosion damage and extend their service life, as well as to improve their safety and reliability. Firstly, the causes and mechanisms of corrosion of underwater steel structures are introduced, and then the corrosion control technologies, such as anti-corrosion coatings, electrochemical corrosion protection, and cathodic protection, which are currently applied in practice, are summarized. Then, the corrosion protection technologies of underwater steel structures are detailed, including coating protection technology, permeation protection technology, electrochemical corrosion protection technology, and cathodic protection technology, and the principles, characteristics, advantages and disadvantages, and applicable scope of various technologies are analyzed. It is found that the corrosion control and protection technologies of underwater steel structures have been widely applied in practical engineering and have achieved significant effects, effectively controlling the corrosion damage of underwater steel structures, thereby extending their service life, and improving their safety and reliability. Finally, the research of this paper is summarized and prospects for the further development of the corrosion control and protection technologies of underwater steel structures are provided, and suggestions for its promotion are made.

Key Words:Underwater steel structures; Corrosion control; Protection technology.
