How to detect and prevent corrosion on your vessel 07-04-2016 The chemical process of corrosion is the natural consequence of mixing metals with salt water, which means getting to grips with it is an essential aspect of boat ownership.... Furthermore, when immersed in sea water, steel is also subjected to galvanic corrosion similar to that which occurs between steel and brass fittings on a boat. In Figure 104: In Figure 104: Zone A is exposed to moist air and salt-laden spray, so is a corrosive zone for steel products.

Galvanic Corrosion NACE International

Galvanic or bimetallic corrosion occurs when two dissimilar metals are immersed in a conductive solution and are electrically connected. One metal (the cathode) is protected, whilst the other (the anode) is corroded. The rate of attack on the anode is accelerated, compared to the rate when the metal is uncoupled. For example, if aluminium and carbon steel are connected and immersed in seawater...
13 Ways to Prevent Galvanic Corrosion 1. Don’t mix metals, or at least use metals as close to each other as possible in the galvanic series. 2.

How To Stop Galvanic Corrosion

For these reasons, galvanic corrosion often attacks ship hulls, offshore rigs, and oil and gas pipelines. Cathodic protection works by converting unwanted anodic (active) sites on a metal's surface to cathodic (passive) sites through the application of an opposing current.

  • Anodising to Prevent Galvanic Corrosion. Galvanic corrosion is a serious issue across the engineering industry and it has a variety of solutions, which …
  • Technical explanation (easily understood) SeaBis Master System eliminates the CAUSE of stray current. Rust, electrolysis, electrolytic action, marina corrosion, boat corrosion and galvanic …
  • Zincs are essential on any metal hull for galvanic protection of the underwater metals (protection against galvanic attack of a less noble metal by a more noble metal), as well as for protection against stray current corrosion.
  • Galvanic corrosion. When (for external application) we match stainless steel with other metals it is appropriate that they be separated by an non-metallic insulator.
