difference between corrosion rusting
Answers
Answer:
corrosion is referred as slow eating up of metal by the action of moisture,water or acid.
rusting is a type of corrosion which is only seen in iron only.
Answer:
Corrosion can occur when the substance is exposed to air or some chemicals. Rusting mainly occurs when a metal is exposed to air and moisture. Corrosion results in the formation of the oxides of metal or salts. ... Rust or rusting can affect only iron and its alloys.
In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen or sulfates. Rusting, the formation of iron oxides, is a well-known example of electrochemical corrosion. ... Because corrosion is a diffusion-controlled process, it occurs on exposed surfaces.
Corrosion is the breakdown of materials due to chemical reactions. It is usually oxidation with air molecules and often in the presence of water. Corrosion also occurs when an acidic or basic material touches another material. When a material corrodes, its physical properties change.
There are five general types of corrosion: galvanic, stress cracking, general, localized and caustic agent corrosion. Galvanic corrosion is extraordinarily common, and occurs when two metals with different electrochemical charges are linked via a conductive path.
