Electrochemical corrosion: main mechanisms
1
2
3
Electrochemical corrosion is a process of metal
degradation.
It occurs due to the interaction of metals with an
electrolyte.
Corrosion reduces the strength and durability of metal
structures

5.

Causes and examples
Exposure to
oxygen,
moisture, and
aggressive
chemicals
Rust on iron
and the gradual
degradation of
copper

6.

Factors affecting the corrosion rate
Temperature and ambient humidity:
accelerate corrosion processes
Chemical composition of the environment:
the presence of salts and acids in the
environment increases corrosion

7.

Contact of the metal with other substances:
may cause galvanic corrosion
Condition of the metal surface:
a rough surface accelerates the process
