What Is Corrosion?

Corrosion is a deterioration of a material caused by environmental interactions. A common form of corrosion is rust.

Corrosion has a variety of negative effects. When metal structures suffer from corrosion, they become unsafe which can lead to accidents, such as collapses.

Then how to prevent corrosion? The following aspects are writing for your consideration.

#1 Metal Type

One simple way to prevent corrosion is to use a corrosion resistant metal such as aluminum or stainless steel. Depending on the application, these metals can be used to reduce the need for additional corrosion protection.

#2 Sacrificial Coatings

Sacrificial coating involves coating the metal with an additional metal type that is more likely to oxidize; hence the term “sacrificial coating.”There are two main techniques for achieving sacrificial coating: cathodic protection and anodic protection.

#3 Protective Coatings

The application of a paint coating is a cost-effective way of preventing corrosion. Paint coatings act as a barrier to prevent the transfer of electrochemical charge from the corrosive solution to the metal underneath.

#4 Design Modification

Design modifications can help reduce corrosion and improve the durability of any existing protective anti-corrosive coatings. Ideally, designs should avoid trapping dust and water, encouragea movement of air, and avoid open crevices. Ensuring the metal is accessible for regular maintenance will also increase longevity.
