impressed current systems

Impressed current systems are used to protect metal structures, like bridges or ships, from corrosion. They work by injecting small, controlled amounts of electrical current into the metal. This electrical flow creates a protective barrier that prevents corrosive elements, such as water and oxygen, from damaging the metal surface. The system includes a power supply, reference electrodes, and protective anodes that distribute the current evenly. By continuously supplying this current, the system significantly extends the lifespan of the structure, reducing maintenance costs and preventing costly failures due to rust or corrosion.
