Corrosion inhibition means precautions to minimize or prevent corrosion and thus damage to equipment and components.Depending on the cause of the corrosion and the requirements on the components or the desired aim and field of application, different processes and procedures as well as corresponding analysis techniques are available.
A common way of protecting against corrosion is to apply barrier coatings such as varnishes. The effect of the protective barrier can be adjusted by functionalizing the coatings with additives such as active or passive corrosion protection pigments, UV stabilizers and biocides.
In addition to a protective coating, the affected materials can ensure a repellent effect against the corrosion-causing media (e.g.hydrophobing). Another possibility is the addition of inhibitors to the media themselves (e.g.closed cooling circuits).
An efficient preservation, which prevents corrosion - especially the formation of white rust - on freshly hot-dip galvanized steel surfaces has been developed. It enables the preservation of the metallic shine of the workpieces during storage, transport and usage.
Corresponding application methods were tested and the effectiveness was proven in condensation water constant climate tests and outdoor weathering.
