A method to reduce the total anode mass of a cathodic protection system by reducing or eliminating the total cathode area is disclosed, the system comprising: a metallic first-layer coating which being anodic to the component or substrate to be protected, bonded to the component or substrate and electrically conductive. A sacrificial anode in the form of a metallic second-layer coating is distributed over the first-layer coating. The second layer coating has an open circuit potential that is equal to the first-layer coating or being anodic to the first-layer coating and to the substrate, the second-layer coating electrically conductive, bonded to the first-layer coating and exposed to the surrounding environment.

Systems and methods of pre-ageing of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor of a reheater. The systems and methods also include heating the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is heated.
