There are two main forms of corrosion each with different characteristics, but the same potential to have a devastating impact on the vessel or structure.
1) Uniform attack: The most common form of corrosion an electrochemical reaction that proceeds over a large area. This is predictable and easily controlled by A) Correct materials, B) Inhibitors, C) Cathodic Protection
2) Galvanic: A potential difference exists between dissimilar metals when they are immersed in a conductive solution. If the metals are placed in direct contact, this potential difference produces electron flow between them. Corrosion of the less corrosion- resistant material is usually increased and attack of the more resistant material is decreased. The less resistant material becomes anodic and the more resistant becomes cathodic. Examples of the galvanic tables are the EMF SERIES and the GALVANIC SERIES for commercially available metals and alloys in seawater.
To stop or prevent these processes you can make sure your anodes are fitted correctly and purchased from a reputable supplier. The anodes are added to your boat to sacrifice themselves, to maintain the integrity of other metals on your vessel or structure, if the anodes are not corroding further investigation would be required as the anodes, once fitted and stable, should start to show signs of corrosion soon after.
Where ever corrosion can or does occur UK Anodes is ready to advise and help solve your problem, so that your investment has a happy and longer life.
