What are the different types of corrosion?
The word corrosion comes from Latin and means to "gnawor chew into little pieces." In metallurgy, it is the chemicalor electro-chemical reaction between a material (usually ametal)and its environment that causes deterioration of themetal and its properties.
Types of Corrosion:
Galvanic (dissimilar materials in an electro-chemical cell)
Erosion Corrosion (flowing corrodent)- Cavitation in corrodent- Fretting (mechanical motion)
Inter granular (including exfoliation)
De alloying (attack of one component in an alloy)
Corrosion Assisted Cracking- Stress Corrosion (tensile stress)- Corrosion Fatigue (cyclic stress)
Hydrogen Damage (embrittlement, blistering, etc.)
Microbiologically Induced Corrosion (MIC)
