to node sacrifiziale perfected for the protection of offshore structures, and process were for its implementation

摘要

A spendable anode for the anticorrosion protection of offshore structures, is constituted by a composite structure in which a first anodic material, which constitutes an external coating on the same anode carrier means, with said material having a more negative electrochemical potential than of the material which constitutes the offshore structure to be protected, is provided, in its turn, with an external coating constituited by a second anodic material the electrochemical potential of which is still more negative than of said first material. Furthermore, some types of anodic material, as well as a process for manufacturing such a spendable anode are specified. IMAGE
