Corrosion Vs Oxidation: Differences?

[koolraj09]

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.
