For the strongest machines and components, manufacturers turn to metal. However, this durable material isn’t without its weaknesses—it can rust when exposed to moisture and an oxidizing agent. If you’re hoping to avoid this and similar chemical reactions, use the following corrosion resistance tips to protect your metal components. 

3 Corrosion Resistance Tips for Metal

1. Prevent Exposure to Moisture

Items with metal that are near water or exposed to humidity such as boats and awnings are especially vulnerable to corrosion. You can protect these items by keeping the area around them dry. This may require the use of fans or an HVAC system to promote airflow and lower humidity. Or, use a drying agent such as talcum or sawdust. To prevent corrosion of underground metal components, such as pipes, surround them in limestone backfill, which will prevent soil moisture from reaching the parts.

2. Use a Passivation Technique

If you can’t limit moisture exposure, or if corrosion is still occurring, coat the metal object in another material, which will shield it from the chemical reaction. When you see a blue-green residue on a metal object or statue, it’s protecting the material beneath. Metal oxide, nickel, and chrome are commonly used for corrosion resistance on metal components.

3. Try Cathodic Protection

Professionals can also protect the metal from corrosion with a chemical reaction. Cathodic protection involves covering a rust-prone metal—such as iron alloy—with a more active metal, like zinc. When the outer layer of zinc begins to corrode, it creates an oxygen compound. This turns the steel into the cathode of an electrochemical cell, making it incapable of corrosion.
