WebGenerally, filiform corrosion occurs on aluminum when it is coated with an organic coating and the system is exposed to relatively high humidities. This type of corrosion is initiated or activated by the presence of electrolytes, particularly chloride, and it is fostered by exposures to warm, humid environments. This type of corrosion is most intense where … WebFiliform corrosion normally starts at small, sometimes microscopic, defects in the coating. Lacquers and "quick-dry" paints are most susceptible to the problem. Their use should be avoided unless absence of an adverse effect has been proven by field experience. Where a coating is required, it should exhibit low water vapor transmission ... WebApr 29, 2024 · The corrosion resistance of electrolytic zinc-coating on mild steel in seawater was investigated.
