Fatigue corrosion and its prevention by Pier Luigi Bonora AITIVA Association and University of Trento, Italy
Fatigue corrosion is one of the least understood and controlled problems, since it is caused by factors and interactions of different kinds and origins. Here, you can read an in-depth analysis of this phenomenon and how it can be prevented.
F
atigue corrosion can be classified among the mechano-chemical corrosion phenomena (Table 1), which all have one aspect in common: the synergism
of increased action. In other words, the simultaneous action of the mechanical and chemical and/or electrochemical contribution reduces the service life of the material or structure much more than the sum of the damages caused by corrosion and mechanical stress acting separately, in any order.
MECHANO-CHEMICAL CORROSION Fretting corrosion
Corrosion due tofluid dynamic action: - Under deposit corrosion - Erosion-corrosion - Cavitation - Impingement attack Stress corrosion Static efforts Fatigue corrosion Periodically variable efforts
