Explanation:
any film or
coating on metal caused by oxidation
Rust is a chemical reaction (oxidation) of iron that occurs over a period of time as the bare metal surface comes in contact with oxygen present in the air or water. Rust "eats" away the metal, rendering it weak and fragile. Therefore, any maneuver that prevents the direct physical contact of iron with oxygen present in air or water will prevent rust formation.Also called iron rust. the red or orange coating that forms on the surface of iron when exposed to air and moisture, consisting chiefly of ferric hydroxide and ferric oxide formed by oxidation.Paint It
Paint the bare metal with any durable acrylic paint. Do not use water-soluable paints, since they will only worsen the rust. Rust will form underneath this type of paint.
Keep Moisture at Bay
Avoid contact with water or moisture. Know that water has a chemical formula H2O, meaning it has 2 parts hydrogen and 1 part oxygen. Oxygen is responsible for the oxidation of iron and therefore forms rust. Clean all iron items periodically and make sure they are dry.
