In simple terms, galvanic corrosion is a type of rust. However, unlike typical rust that’s caused by moisture exposure, galvanic corrosion develops when different types of metals come into contact with each other. It frequently occurs around supports and screws and is most common in industrial settings and coastal areas.
In addition to gutter guard cleaning, there are a few other things you can do to reduce the risk of galvanic corrosion.
The Science Behind Galvanic Corrosion
When two different types of metal come into contact with each other, galvanic corrosion can occur. A galvanic scale can be used to determine whether a metal is electropositive or electronegative. Corrosive metals are electropositive, while non-corrosive ones are electronegative. When electropositive and electronegative metals come into contact with each other, corrosion can occur. The further away the two types of metal are from each other on the galvanic scale, the faster the speed and the effect of the corrosion will be.
How to Prevent Galvanic Corrosion
Corrosion can be kept to a minimum by doing the following:
-
Applying non-metallic coatings to electropositive metals
-
Limiting the amount of time metal surfaces are left wet
-
Separating metals with non-absorbent, non-conductive materials (elastomeric sheets, sealant, gaskets, tape, waterproof paper, etc.)
