What is Rust?
The most common example of is this the rusting of iron, a natural chemical reaction in which the iron combines with both oxygen and water to form hydrated iron oxide. The oxide is a solid that is soft, somewhat bulkier than the iron from which it is formed, relatively weak, and brittle.
Alloying
The alloying method is the most effective, but the most expensive. A good example is stainless steel, nickel and other metals are alloyed with the iron; this alloy is not only absolutely rustproof but will even resist the action of such corrosive chemicals as hot, concentrated nitric acid.
