What is an Anode and Electrolysis?
The anodes
All boats have one or more anodes, which is usually necessary change every year.
But why?
Because simply the anode undergoes electrolytic corrosion for your boat.
What is it?
Electrolysis is an electrical current that forms between two metals immersed in water.
What are the anodes for?
The anodes, always made of very soft metal, will channel this phenomenon by cashing the electrolysis for your boat and destroying themselves to avoid other metal parts of the edge destroying.That's why we're talking sacrificial anodes.
The different anode materials
The best anode materials are zinc and aluminum.Being the softest metals, they are the ones that attract the most electrolysis phenomenon.
Generally, we use the zinc or aluminium to protect the other parts, both being very subject to electrolysis.
DAM Marine sells anodes of the brand Performance Metals Product, which are anodes having an alloy corresponding to the mIL-DTL-24779B(SH) military standard.
Indeed, this alloy ZincAluminium andIndium offers better protection (from 30 to 50% better than classic zinc anodes) and allows the anode to remain clean.
Mount its anode
There are some precautions to take when you mount your anode on a metallic piece:
- Attention to electrical leaks : if your electrical network is poorly isolated, the electrolysis phenomenon will amplify.
