Reference Answer
### Definition of Corrosion Control
Corrosion is the gradual destruction of materials, usually metals, by chemical or electrochemical reaction with their environment. In the marine context, this is primarily electrochemical corrosion due to the presence of seawater, which acts as a highly effective electrolyte.
**Corrosion Control** is the comprehensive strategy and application of specific techniques to prevent or mitigate the rate of this material degradation. The primary objective is to maintain the structural integrity, operational efficiency, and safety of the ship's hull, machinery, and equipment, thereby extending their service life and reducing maintenance costs.
