What is rust and what causes it? Rust is a kind of iron oxide and it occurs when iron combines with the oxygen in the air causing it to wear away. It is an orange-brown tarnishing that builds upon the metal. Rust can affect iron as well as its alloys like steel. If you have iron, water, and oxygen you will definitely get rust.

Ways to prevent Metal from rusting
Rust can weaken your metal’s strength by making them fragile and this will also shorten their lifespan. When you think about keeping your metal in good quality, preventing it from rust is the first problem. If your metal is exposed to the outside conditions and if the atmosphere is humid, then there is a great risk of rusting.
These are the best ways to prevent metal from rusting.
Galvanizing
It is a method to prevent rust. In this method, the iron or steel object is coated with a thin layer of zinc. It creates a protective coating that prevents water and oxygen to enter the iron causing it to rust. There are different types of galvanizing hot-dip galvanizing, pre-galvanizing, and electro galvanizing. Zinc is more reactive than iron that’s why its oxides in proclivity to the iron object.
Corten or weathering steel
You can also use weathering steel which is also known as COR-TEN steel. It contains about 21% alloying elements which include chromium, copper, nickel, and phosphorus. These alloys reduce the corrosion rate with time. COR-TEN steel is cheaper than stainless steel.
Stainless steel
Stainless steel is an alloy and contains almost 11% chromium. This alloy forms a protective layer of chromium oxide which acts as a protective shield against rust. This protective shield will reform if damaged and you can also increase its resistance by adding nickel.
Proper design
Metal should be designed in such a way that it allows the air to freely flow around it. There should be proper planning before designing metal that will reduce the risk of rusting. Crevices and cavities should not be used and joints of metal should be welded. Consider the drainage holes of water.
Bluing
It is a process in which parts of steel are immersed in the solution of water, potassium nitrate, and sodium hydroxide. It is a useful technique because it offers protection against rust to the small parts of the steel. It is called Bluing because at the end of the process it gives the appearance of blue-black. It is also used while making clocks and other metalworks.
Regular maintenance
Regular maintenance will help to stop forming rust and cease the process that has accrued. It’s really important to remove the rust that has formed and you can use a razor blade for small areas. You can use warm water and soap to remove surface dirt. After all of this cleaning apply a rust-resistant coating on the surface.
Fozz
It is a blend of phosphoric acid and other chemicals like extenders and wetting agents. It dissolves rust and prevents the surface from further rusting. Fozz is not a paint but a kind of primer which set-up metal so that the paint can adhere.
Powder coating
When a dry powder is applied to a clean surface this is called powder coating. Then the object is heated and the powder is turned into a thin layer. Acrylic, polyester, nylon, and vinyl can be used for this purpose. These powders are applied using an electrostatic spray process. A charged non-conducting powder is sprayed on an electrically charged object.
Organic coating
A cheap and effective method to protect against rusting is by applying an organic coating. This organic coating will serve as a barrier for the corrosive elements. Coating of oil is the best for preventing the penetration of water and oxygen.
These were the most popular 9 methods of preventing your iron from getting rust. Hopefully, this article will help you a lot but besides all these ways there are other ways also. If you want to dig deeper you can by reading more and more articles on the internet. If you are facing any problem regarding the Ptcl speed test of your internet.
