Corrosion Vs Oxidation: Differences?

Click For Summary
SUMMARY

Oxidation and corrosion are distinct processes, although they often occur simultaneously. Oxidation refers to the chemical reaction where a substance loses electrons, typically involving oxygen, while corrosion specifically pertains to the deterioration of materials, particularly metals, due to environmental factors. Notably, not all oxidation leads to corrosion, and not all corrosion involves oxidation. Understanding the nuances between these processes is crucial for material longevity and performance.

PREREQUISITES
  • Basic chemistry concepts, particularly redox reactions
  • Knowledge of material science, especially metal properties
  • Understanding of environmental factors affecting materials
  • Familiarity with high-temperature oxidation processes
NEXT STEPS
  • Research the mechanisms of high-temperature oxidation in metals
  • Explore corrosion prevention techniques for various materials
  • Study the role of environmental factors in corrosion rates
  • Learn about the differences between galvanic corrosion and uniform corrosion
USEFUL FOR

Material scientists, engineers, and anyone involved in the maintenance and longevity of metal components will benefit from this discussion.

Hi guys,
Until now I thought that oxidation and corrosion are the same. But I am not sure. Are they one and the same?
Why oxidation at high temperatures is important? How does that reduce part life?
Thanks.

Not every corrosion requires an oxidation, and not every oxidation counts as corrosion.

But quite often they go hand in hand.
