Abstract

The present invention develops dies, moulds, tools, workpieces and structures with active protection against corrosion (cathodic protection) in cooling circuits, often internal, independent of its complexity. Moreover, the protection can be renewed if considered appropriate. The protection is achieved through a thin coating layer which contains metallic elements more electronegative than the substrate to be protected and which is properly adhered to the mentioned substrate in order to ensure an efficient cathodic protection.
