Corrosion and protection of metals in marine media

The fight against corrosion starts with the choice of materials and the design of parts . By virtue of the facts established above, in the case of the marine environment it is imperative:

• to avoid or minimise all containment zones, which favour the mechanisms of localised corrosion (pitting or crevice corrosion);

• not to assemble together materials with non-compatible electrochemical properties, which risks encouraging galvanic corrosion.

When designing a structure for immersion in the sea, an assessment must be carried out to define which alloys...
