Definition of Corrosion Corrosion of Metals can be defined as the destructive attack of a metal thrgough interaction with its environment |
||
| The corrosion of a metal is a chemical process by which the metai is oxidized. The tendency to corrode in a given environment varies with the particular metal. | ||
|
Corrosion is the result of a chemical reaction between a metal and its
surroundings during which the metal is oxidized. |
||
|
Corrosion is the deterioration of a material due to interaction with its
environment. It is the process in which metallic atoms leave the metal or form
compounds in the presence of water and gases. Metal atoms are removed from a
structural element until it fails, or oxides build up inside a pipe until it is
plugged Ref: DOE FUNDAMENTALS HANDBOOK MATERIAL SCIENCE Volume 1 of 2 |

|
Corrosion can be defined as the deterioration of material by reaction to
its environment. The corrosion occurs because of the natural tendency for most
metals to return to their natural state; e.g., iron in the presence of moist air
will revert to its natural state, iron oxide. Metals can be corroded by the
direct reaction of the metal to a chemical; e.g., zinc will react with dilute
sulfuric acid, and magnesium will react with alcohols Ref: NASA - CORROSION CONTROL AND TREATMENT MANUAL - TM-584C REVISION C |
