- Eating away and eventual destruction of metals and alloys by chemical attack. The rusting of ordinary iron and steel is the most common form of corrosion. Rusting takes place in moist air, when the iron combines with oxygen and water to form a brown-orange deposit of rust (hydrated iron oxide). The rate of corrosion is increased where the atmosphere is polluted with sulphur dioxide. Salty road and air conditions accelerate the rusting of car bodies.

What is the meaning of the corrosion?
Corrosion is a gradual chemical or electro-chemical attack on a metal by its surrounding such that the metal is converted into an oxide,salt or other compound
What is the Hindi meaning of corrosion?
Corrosion is a gradual chemical or electro-chemical attack on a metal by its surrounding such that the metal is converted into an oxide,salt or other compound
What is metal corrosion?
Metal Corrosion or Metallic Corrosion can be defined as the destructive attack of a metal through interaction with its environment.The most common example is Rust, an iron oxide Fe2O3, that is the consequence of the Corrosion process of Iron.
What is immersed corrosion?
Immersed Corrosion refers to a type of metal corrosion when the metal is immersed in a liquid.
What is corosion?
Corrosion of Metals can be defined as the destructive attack of a metal through interaction with its environment
Is corrosion of aluminum metal a chemical?
Corrosion is a chemical process.
What metals are most affected and least affected by metal corrosion What causes metal corrosion Hows is metal corrosion caused by water and how is it related to it?
Corrosion is a chemical reaction; corrosion of iron is the reaction with water in the presence of oxygen. Metals as Pt, Au, Ta, Rh, Ru, etc are less sensible to corrosion.
Is rust a form of corrosion?
Yes. Rust is oxidation of the metal, a form of corrosion (chemical destruction) that weakens metal.
Which metal could be used to coat another metal to protect it from corrosion?
Tin could be used to coat another metal. It is done to prevent corrosion.
Is Corrosion is a physical property of metals?
No, corrosion is a chemical change of the metal involved.
In which kind of environment pitting corrosion happen?
Pitting corrosion generally happens in an oxygen deficient environment where the metal is surrounded by an ionic solution with chloride, bromide, or fluoride ions. A scratch in the metal under these conditions does not allow the metal [such as stainless steel] to reform the thin oxide layer which would normally protect the surface.
What is corrosive?
Corrosion is a chemical reaction in which molecules break down due to a chemical reaction with its surroundings. Most often, corrosion is the electro-chemical oxidation of a metal (such as iron "corroding" to form iron oxide, a.k.a. rust). Corrosion is deterioration of a substance, usually metal. Corrosion is slow and continuous eating away of metal by the surrounding.
