There is always a chance of corrosion with any metal. However, before corrosion becomes an issue, it can be controlled, slowed down or stopped. It is possible to stop corrosion on metal. Just like, anti rust coating can be used by manufacturers. Then, users can take preventative steps to increase its durability.
This blog will help you understand corrosion and how to stop it. Keep reading to learn more.
What is Corrosion?
When a metal reacts with an oxidising agent in its surroundings, corrosion results. This chemical reaction can make the metal rust with time and also tarnish. This makes the outer surface not as appealing as before. All types of metals are different in their electrochemical properties. Just like, tools made of iron become rusty due to the effects of moisture. While, under the effects of the weather, a copper roof will develop a tarnished look.
5 Ways to Stop Corrosion on Metal
There is no universal perfect solution to stop corrosion on metal. Since there are numerous types of metal and thousands of possible uses, manufacturers use numerous methods to stop corrosion on metal. Some of the many ways are:
- Design Considerations
Corrosion can be stopped right from the design stage. Do not use shapes that cause water or dirt to accumulate. Make sure that water may flow freely through all metal parts. Smooth curves are preferable instead of corners with sharp edges. Leave space for inspections. Select joining techniques that prevent corrosion.
- Use Protective Coatings
The metal is protected from its surroundings by coatings. Paint is one of the most widely used coatings that can stop corrosion. There are also special anti-corrosion paint options. These work even better than normal paint. They stick well to metal and do not allow water or air to get through. Others have chemicals that are used to fight corrosion.
- Apply Anti-Corrosion Silicone Coating
Anti-corrosion silicone coating can be used to stop corrosion on metal. It is easy to use. A thin layer (8-12 mils) gives good protection. You only need one coat, and this is both faster and affordable. It sticks to the metal without prep work. This coating prevents the spreading of the rust. It is very durable and does not change colour much, even after long exposure.
- Keep Metal Clean and Dry
Both water and dirt cause corrosion. Clean metal items with a soft cloth often so that you can remove dirt and moisture from the surface of the metal. This must be followed by drying of the metal. Any item that is exposed to the outdoors should be covered when not in use. This keeps rain and dew off. In humid regions, use a dehumidifier to reduce the humidity in the room.
- Use Cathodic Protection
One technique that uses electricity to stop corrosion on metal is cathodic protection. It works by making the metal a cathode in an electrical circuit. This helps to avoid the formation of chemical compounds, which leads to corrosion. Sacrificial anodes and impressed currents are the two types.
To conclude, stopping corrosion is necessary for protecting metals from being damaged and for making them perform their functions effectively. This means that, through the use of anti corrosion coating, keeping metal dry and clean and other above-mentioned methods, you’ll be able to safeguard your metal products. It is also important to select the appropriate method in the process. If appropriate measures are taken, your metal parts will have a longer service life than expected.
