Impressed Current Anodic Protection (ICAP)
Impressed Current Anodic Protection (ICAP) is a method used to protect metal structures, like ships or pipelines, from rusting or corrosion in harsh environments. It works by applying a controlled, small electrical current to the metal, making its surface act as a protective anode. This process shifts the metal’s surface to a more stable, corrosion-resistant state, preventing rust formation. The system uses an external power source and special electrodes to ensure continuous, effective protection, extending the lifespan of the structure and reducing maintenance costs.
