Is non rusting metal a physical change?
If by non rusting you mean it is in the same state it was made in then it wouldn't be part of any change. But if something is rusting it would be a chemical change because the metal is changing composition and it is not the same metal it was in the first place.
Is rusting iron a physical change in science?

Why is rusting a chemical change?
Rusting is a reaction which combines molecules to form other molecules: metal + oxygen -> rust. The definition of a chemical reaction is molecules turning into other molecules, so rusting is a chemical reaction.
What are the ways of preventing rusting?
Rusting is the oxidation of iron. To prevent rusting you must prevent oxygen from coming into contact with the product. This is normally acheived by applying a barrier of oil in working environments. Products are available for storing materials for long periods to avoid rusting. These have a more waxy nature than oil and would not be suitable to use to stop rusting in a mechaincal item. Of course if you want to prevent rusting and for it to look nice. various paints and lackers can be applied. Chemical coatings can also be applied to prevent rusting. Or simply keep the item clean and dry and rusting can be slowed.
