can we permanently prevent the rusting of an iron article by applying a layer of paint on its surface? The simplest answeris no. The reason being that almost any painted surface willeventually be damaged allowing oxidation of theiron(rust).

Likewise, why do we apply paint on iron articles Brainly?

Iron articles are painted because it preventsthem from rusting. When painted, the contact of ironarticles from moisture and air is cut off. Hence,rusting is prevented. So presence of air and moistureis essential for rusting to take place.

Why do we paint steel?

A clean surface ensures better paint adhesion tothe surface, which will increase paint job durability andprolong the lifespan of metal surfaces. When metalsurfaces are exposed directly to the elements, such as moisture,rain and sunlight, they'll rust or corrode.

How is galvanized steel made?

Galvanized steel is a carbon steel thathas been coated with zinc. The most common method of zinc coatingis the hot-dip process. When the material is removed from the zincbath and cooled a reaction to the oxygen in the air occurs. Thereaction causes the zinc to become part of the steel (aniron-zinc alloy bond).

Will painting over rust slow it down?

Yes, it does. Rust is weak, so any paintover it will hold weak.

Will rust spread if kept dry?

Spreading. Rust does not spreadthrough contact like a biological infection. This means thatif one part of the piece is exposed to water, oxygen, andelectrolytes but the rust of the piece is kept cleanand dry, the protected metal will not rest at therate of the wet metal.
