How to Prevent Filiform Corrosion

Filiform corrosion is a tricky form of corrosion that often occurs under thin coatings. It is typically formed in a threadlike filament, from which it derives its name. It commonly develops on metallic surfaces covered or coated with a thin film, often meant to prevent or deter corrosion from forming. Filiform corrosion thrives in this environment, where other types of corrosion are usually discouraged. Check out this guide for ideas on avoiding filiform corrosion in your metals.

Learn to identify filiform corrosion

There are many different classifications and types of corrosion that could be affecting your metal items. To identify filiform corrosion, you will need to look at and under the metal’s coating rather than a more common type, such as galvanic corrosion. With filiform corrosion, you may notice the metal’s coating bulging, appearing fuller than normal, or even cracking. This is a sure sign that filiform corrosion has invaded your metal. This is one of the forms of corrosion that is visible to the naked eye. The first step in preventing filiform corrosion is knowing how to recognize it before it becomes a large-scale problem.

Control the humidity levels

Wherever your metal is located, be sure to keep the humidity under control, if possible. High levels of humidity contribute to more rapid filiform corrosion formation. Suppose your metal is located where temperature and humidity control is possible. In that case, it is worth the investment to save your metal and its coatings from the costly damage of filiform corrosion. Humidity creates more moisture in the air, which can get trapped under metal coatings.

Use brittle coatings

Using a brittle coating over your metal materials is more advantageous if you’re worried about the development of filiform corrosion because it will not contain moisture in the same way a strong, durable coating will. This can help the moist conditions detach from the metal before it corrodes.
