Key Features:
- The combined action of stress and corrosion: Exacerbating the degradation of the material with mechanical stress and chemical corrosion acting together.
- Crack initiation and growth: Start and propagate cracks even under lower stress levels with time.
- Metal being prone: Steel, aluminum, and related metals are widely encountered with corrosion fatigue in marine, aerospace, and chemical applications.
Corrosion fatigue is of the utmost importance since it inevitably compromises the life and reliability of critical components. For the aerospace industry, the presence of moisture along with fluctuating stress on aircraft structures makes these components especially vulnerable to corrosion fatigue, which in turn is of great concern regarding safety and performance issues. In marine applications, it is the pipelines and ship hulls that are investigated for corrosion fatigue and usually warrant protective coatings and inspection on a regular basis. Improvements in material science and surface treatment techniques have been and will continue to be avenues for advancement in resisting corrosion fatigue and therefore enhancing durability in several applications.
