Types of Corrosion, Oxidacion, Combustion, Metal Corrosion

Corrosion is the disintegration of a material into its component atoms by chemical reactions with the environment. The most common use of the word, it means a loss of electrons in metals react with water and oxygen. Weakening of iron due to oxidation of iron atoms is a well known example of electrochemical corrosion. This is called rust. This type of injury typically produces oxide (s) and / or salt (s) of the original metal. Corrosion can also refer to materials other than metals, such as ceramics or polymers. Although in this context, degradation of pastures are more common.


Corrosion can be categorized in some common types:
uniform corrosionpitting corrosiongalvanic corrosioncrevice corrosionconcentration cell corrosiongraphitic corrosion. To learn more about these corrosion visit Types of corrosion.

Most structural alloys corrode just from exposure to moisture in the air, but the process can be greatly influenced by exposure to certain substances (see below). Corrosion can be concentrated locally to a hole or crack, or it may extend over a large area to cause a general deterioration. While some efforts to reduce corrosion to simply redirect the damage in less visible and less predictable forms, controlled corrosion treatments such as passivation and chromate conversion increases the corrosion resistance of a material.

Some metals are more intrinsically resistant to corrosion than others, either because the fundamental nature of the electrochemical processes involved or from details on how the shape of the reaction products. For examples, see the galvanic series. If a more sensitive material is used, many techniques can be applied to a point of production and use of their equipment to protect against damage.
