Corrosion - Beneteau Iron Keel Restoration
The best way to treat an iron keel that is rusting is to sandblast the entire surface and apply an epoxy based coating system. But that's not always feasible or desirable.

Critical plane analysis refers to the analysis of stresses or strains as they are experienced by a particular plane in a material, as well as the identification of which plane is likely to experience ...
Metal dusting
Metal dusting is "a catastrophic form of corrosion that occurs when susceptible materials are exposed to environments with high carbon activities." The corrosion manifests itself as a break-up of bulk...
Galvanic corrosion
Galvanic corrosion is an electrochemical process in which one metal corrodes preferentially to another when both metals are in electrical contact, in the presence of an electrolyte. This same galvanic...
