This template is a photograph of rusted antique metal with a brand new screw fastening in it. Rusting occurs when metal comes into contact with water and oxygen. If salt is present in the water then it tends to rust more quickly. To prevent rusting, metals can be galvanised, painted or plated to restore the old metal back to before oxidisation.
This could be used for a presentation on engineering, ships, water, air, metals or design.
