CORROSION - Coggle Diagram
CORROSION
Depending on the medium
Chemical Corrosion
To exposure with oxygen and temperature variation.
Electrochemical corrosion
It involves a transport of electricity through an electrolyte
Galvanic corrosion
when two different metals are in contact, one active and the other noble
Depending on the form
Uniform corrosion
Attack is homogeneous over the entire metal
Localized corrosion
Plate corrosion
Attack is more widespread in some areas
Pitting corrosion
Attack is located at isolated points
Friction corrosion (frettin)
Produced by small movements or vibrations
Cavitation corrosion
It is generated by the contact of the surface of the metal with some liquid
Microbiological corrosion
Biological organisms originate the crack or proceed as accelerators
Stress corrosion
It is due to the appearance of internal stresses after cold deformation.
Intergranular corrosion
located at the grain boundaries.
Corrosion by erosion
Caused or accelerated by the relative movement of the metal surface and the medium.
