When any metal containing iron is exposed to air and water, it forms rust. You can identify rust when you see orange-brown flakes of iron oxide on the meal. This type of corrosion can be highly destructive, as well as unsightly. In this article, we will explore some tips on how to prevent rust.
Keep It Clean and Dry
Water is a prime suspect when it comes to rust. This is because the oxygen in water molecules combine with iron to form rust. That is the reason why metals left outdoors, such as gates, tanks, or cars, are more likely to rust. Install a dehumidifier to prevent rust formation on objects kept in humid indoor environments, such as a basement or garage.
Cracks or scratches in the metal can expose more metal and hold water, which allows it to remain in contact with the iron. The reason behind cold rolled steel being more resistant to corrosion than hot-rolled is cold rolling forms a smoother surface without texture that can trap and hold water.
Apply a Protective Coating
Dipping metal objects into a bluing solution of water, potassium nitrate, and sodium hydroxide provides strong resistance to corrosion. Commercial rust prevention products available on the market in the form of cloth wipes can also protect metal objects like vehicles and tools.
Rust takes very little time to spread; therefore, it is important to scrape it off as soon as it appears. Then scrub the metal with warm water and soap and apply a protective coating to prevent further oxidation.
Use Stainless Steel
Stainless steel alloys resist rust because, along with containing iron, it contains a high percentage of chromium. Chromium reacts quicker than iron. The chromium in the alloy oxidizes rapidly, forming a protective layer of chromium oxide on the metal surface. This layer prevents oxygen from reaching the underlying steel.
