🔋 10. The Truth About Zinc Anodes and Corrosion
🗣️ The Myth: "My anodes look brand new after the season – my protection is perfect!"
⚙️ The Technical Reality:
Anodes are sacrificial. Their sole purpose is to be destroyed instead of your expensive engine components.
⚠️ The Hidden Risks:
If they are intact, they lack electrical continuity, or the metal is wrong for the water. Instead, your bronze thru-hulls and propellers are being eaten by galvanic currents.
🔬 The Evidence Method (NDT & Analys):
We deploy a Silver/Silver Chloride (Ag/AgCl) reference electrode to map the vessel's cathodic protection down to the millivolt.
⚖️ The Chairman's Verdict:
Galvanic corrosion is silent and incredibly expensive. We measure and prove the stray currents before the metal vanishes.
