Corrosion and its Types
What do you mean by Corrosion?
As a native process, corrosion is the process of converting pure metal into a much more robust and robust form such as oxides or hydroxides. There is no doubt that it is a constant of metals because of the artificial action with which they are enclosed.
During the course of the process, it degrades and erodes the metals, thus destroying their power, beauty, and durability. It is common for materials to be divided into two categories, which are chemical factors and physical factors, as a general rule.
Varieties of Corrosion
Crevice Corrosion
Corrosion in crevices occurs when there is little space and interval to produce liquid and there is no suitable body process to process it. Whenever crevice corrosion occurs, it adds a great deal of risk to the chance of crevice corrosion occurring in the near future. Because of the connective sign between the metallic floor and corrosive fluid, crevice corrosion will be damaged by the mechanical injury resulting from the mechanical action of the fluid.
Corrosion Fatigue
Fatigue of ore will grow in a corrosion climate, and then it will be called corrosion fatigue, meaning the defeat of matter due to repeated application of pressure. There can be a development of this condition if the fatigue resistance of a metal is stopped.

Galvanic Corrosion
A galvanic pair is formed between two types of the matter when they situate and connect in corrosive potassium, and it is the anode and cathode that form the galvanic pair. It is necessary to be in electrical contact with an electrolyte for galvanic corrosion to occur.
Environmental Cracking
Cracking under the influence of environmental conditions refers to corrosion that occurs as a result of a combination of ecological conditions damaging the material, along with synthetic, pressure, and strain-related outcomes that can actually occur simultaneously.
There are three types of corrosion in the environment below: corrosion fatigue, hydrogen-induced cracking, stress corrosion cracking, and liquid metal, embrittlement, and stress corrosion cracking.
Intergranular Corrosion
A form of corrosion called intergranular corrosion occurs when corrosion appears on the granular field, and in this case, the seed is not damaged. It is evident that there is a variation in a reaction against a pollutant when both the original source and the seed margin are different.
