FAQ

What is cathodic protection, and why is it important for ships and marine structures?

Cathodic protection controls corrosion of metal surfaces in marine environments by making them the cathode of an electrochemical cell. It prevents costly repairs and premature replacement of ships and structures.

What are sacrificial anodes, and how do they work?

Sacrificial anodes are made of a more active metal alloy, such as aluminum-zinc, than the protected metal. When connected, these anodes corrode preferentially, sacrificing themselves to prevent corrosion.

Why choose Comac's aluminum-zinc anodes over other anode materials?

Comac's aluminum-zinc anodes offer higher driving voltage, lower consumption rate, and longer lifespan compared to pure aluminum or zinc anodes, providing better corrosion protection.
