The final net anode mass maf and final volume Vaf is given by: maf = mai ⋅ (1 – u) (18) maf Vaf ... WitrynaGalvanic anodes have several limitations that must be considered: • The driving force available is very limited • The service life and efficiency tend to be low requiring either …
Witryna13 maj 2024 · The impressed current anodes are usually made up of strong insoluble materials like titanium. They may be disc or stripe-shaped. Either 2 or 4 units are placed symmetrically forward and aft of the vessel. The anodes are welded on doubler plates onto the hull surface so as to be completely flush to the outside hull plate.
