Corrosion vs. Rust

Corrosionnoun

The act of corroding or the condition so produced.

Corrosionnoun

A substance (such as rust) so formed.

Corrosionnoun

(chemistry) Erosion by chemical action, especially oxidation.

Corrosionnoun

(by extension) The gradual destruction or undermining of something.

Corrosionnoun

The action or effect of corrosive agents, or the process of corrosive change; as, the rusting of iron is a variety of corrosion.

Corrosionnoun

a state of deterioration in metals caused by oxidation or chemical action

Corrosionnoun

erosion by chemical action

Corrosion

Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, carbonate or sulfide. It is the gradual destruction of materials (usually a metal) by chemical and/or electrochemical reaction with their environment.

Rustnoun

The deteriorated state of iron or steel as a result of moisture and oxidation.

Rustnoun

A similar substance based on another metal (usually with qualification, such as "copper rust").

Rustnoun

A reddish-brown color.

Rustnoun

A disease of plants caused by a reddish-brown fungus.

Rustverb

(intransitive) To oxidize, especially of iron or steel.

Rustverb

(transitive) To cause to oxidize.

Rustverb

(intransitive) To be affected with the parasitic fungus called rust.

Rustverb

To (cause to) degenerate in idleness; to make or become dull or impaired by inaction.

Rustnoun

The reddish yellow coating formed on iron when exposed to moist air, consisting of ferric oxide or hydroxide; hence, by extension, any metallic film of corrosion.

Rustnoun

A minute mold or fungus forming reddish or rusty spots on the leaves and stems of cereal and other grasses (Trichobasis Rubigo-vera), now usually believed to be a form or condition of the corn mildew (Puccinia graminis). As rust, it has solitary reddish spores; as corn mildew, the spores are double and blackish.

Rustnoun

That which resembles rust in appearance or effects.

Rustverb

To contract rust; to be or become oxidized.

Rustverb

To be affected with the parasitic fungus called rust; also, to acquire a rusty appearance, as plants.

Rustverb

To degenerate in idleness; to become dull or impaired by inaction.

Rustverb

To cause to contract rust; to corrode with rust; to affect with rust of any kind.

Rustverb

To impair by time and inactivity.

Rustnoun

a red or brown oxide coating on iron or steel caused by the action of oxygen and moisture

Rustnoun

a reddish-brown discoloration of leaves and stems caused by a rust fungus

Rustnoun

the formation of reddish-brown ferric oxides on iron by low-temperature oxidation in the presence of water

Rustnoun

any of various fungi causing rust disease in plants

Rustverb

become destroyed by water, air, or an etching chemical such as an acid;

Rustverb

cause to deteriorate due to the action of water, air, or an acid;

Rustverb

become coated with oxide

Rustadjective

of the color of rust

Rust

Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides (Fe2O3·nH2O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), and is typically associated with the corrosion of refined iron.
