The oily layer prevents water and air from reaching the metal's surface and causing the metal to rust.
Rusting of iron can be prevented by painting,oiling,greasing,galvanising,chrome plating,anodising or making alloys
prevents rusting.
Metals are prevented from rusting by providing a coating on the surface of the metal to stop the metal from mixing with oxygen and H2O in the air. Please do not copy this word for word. I am handing this in for a report. Thanks!
any metal covered in zinc. zinc is used to prevent metals from rusting
Some other metals commonly used to prevent rusting include stainless steel (which contains chromium), aluminum, and galvanized steel (which is coated with a layer of zinc). Copper and nickel can also be used for certain applications.
Rust is specifically oxidized iron and the most common way to prevent it is by painting it. Additionally a common pre-consumer method is to electrochemically add a layer of zinc on the iron which is commonly seen in galvanized nails. The zinc will only be oxidized for the first few nanometers of the layer and it will prevent oxygen from reaching the inner iron.
Painting will be a good option to prevent rusting.
To avoid rusting
Most of the metals will oxidize, but the only one for which that process is called "rusting" is iron.
You can reduce the air humidity is less oxidizing metals.
Depending on the material that the gates are made of, rust is a potential issue. If they are made from wood rusting won't take place. Additionally, there are many kinds of treatment for metals that can delay or even prevent rusting from happening.
Coating prevent the iron from contacting air and moisture. So it prevents iron from rusting.
