Corrosion Fatigue |
|||
|
|
Failure of a part when it is exposed simultaneously to corrosive attack and cyclic stresses is called corrosion fatigue. This type corrosion seems to begin at localized areas on the metal surface when the protective film on the part is reftured by the push - pull bending induced by cyclic stesses. |

|
The corrosive agent attacks the vulnerable localized area, causing a fissure ( corrosion fit ) to form. The pit continues to deepen until the part is so weakened that ultimate in cracking occurs the part breaks. This simple explanation does not intend to imply that only one pit per part is allowed. However, since the corrosion is highly localized, most of the part will be unaffected. Unfortunately, this is of little consolation if the part breaks. Fretting Corrosion.. read more... |
