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!
by prevent the object away from the contact of oxygen. it can prevent an object from rusting.
Painting will be a good option to prevent rusting.
Bluing (eg firearms), galvanizing (Zinc coating), electroplating with cadmium, brass or other protective metals, and paint are coatings used to prevent rust.
Not, as of yet, but you could try it. rusting can only be prevented or treated thereafter.
By preventing rusting of iron in bus not being sarcastic at all
Iron can be coated with copper, but it is 3 times the cost
any metal covered in zinc. zinc is used to prevent metals from rusting
It decreases rusting but doesn't totally prevent it.

Slow oxidation

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.
Electrolysis can be used to prevent rusting because metals give away electrons and if the metal is wired up to the negative electrode it gains electrons which means it will prevent rusting as it isn't losing electrons.
Most of the metals will oxidize, but the only one for which that process is called "rusting" is iron.
