Corrosion Protection Methods: Know How it Protect Your Metal

Posted on: January 29th, 2019 by byersbushblog

Corrosion refers to the deterioration of metal.  This is caused by chemical reactions that occur between the metal itself and the surrounding environment.

One example of corrosion is rust.  The rate of corrosion can be slowed or stopped by using corrosion protection methods.

Let’s take a look at some of the methods that are used to protect surfaces from corrosion.

Environmental Modification Methods

As was previously stated, corrosion occurs as a result of chemical reactions that occur between the metal itself and the gases in the surrounding environment.

Therefore, corrosion can be slowed or stopped by removing the metal from the offending environment.

This can include simple steps, such as storing metal objects indoors, where they won’t be exposed to rain water.  It can also mean adjusting the environment that is affecting the metal.

One example of adjusting the environment in order to protect the metal is the water that is used in water heaters.

If the water is treated with softeners, the rate of corrosion of the metal water heater tank will be slowed significantly.

Choice of Metal

Corrosion can also be prevented by choosing a type of metal that is suitable for the purposes at hand.  Unfortunately, there is no metal that is impervious to corrosion.

However, selecting a metal that is appropriate for the environment and conditions can greatly reduce the rate of corrosion.

Certain alloys, such as Hastelloy nickel alloys, Nirosta steels, and Timetal titanium alloys can protect against corrosion in specific environments.

Paying attention to surface conditions also helps to slow corrosion.  Any cracks or wear and tear on the surface will increase the rate of corrosion.  Maintaining optimum surface conditions will help to reduce corrosion.

Corrosion Inhibitors

A corrosion inhibitor is a chemical that reacts with either the metal surface or the environment in order to interrupt the action of corrosion.

Inhibitors create a protective film on the metal surface. Corrosion inhibitors are often used in industries such as petroleum refining, oil and gas exploration, chemical production, and water treatment facilities.

One of the benefits of corrosion inhibitors is that they can be used as a form of corrective action rather than solely as preventive action.

If rust or corrosion is noted on a metal surface, a corrosion inhibitor can then be applied to stop the corrosion process.

Protective Coatings

Protective coatings, such as paint or powder coating, are also used to protect metal from corrosion.

Powder coating is a process that involves applying a protective outer layer to metal, thereby increasing its ability to resist rust, corrosion, and exposure to natural elements.

It is often used to coat and protect items that will be used outdoors, such as sporting equipment, patio furniture, or car parts.

The powder that is used in powder coating is composed of phosphates and a blend of fine metal particles, like titanium.  The exact combination of ingredients can vary from one manufacturer to another.

In any case, the coating is a fine powder that is sprayed on to metal substances and baked at high heat, which causes it to cure and form a durable finish.  It will prevent forms of deterioration, including rust, corrosion, and weather damage.

Powder coating a product is advantageous because it increases durability without significant increasing weight.
