Vibration corrosion cracking

Vibration corrosion cracking is a special form of corrosion that occurs in metal components under repeated mechanical stress. This type of corrosion is the result of a combination of cyclic stress and chemical reaction that can lead to cracking and structural damage.

Vibration corrosion cracking often occurs in environments where metal components are exposed to vibration or oscillation, such as in vehicles, machinery, bridges or pipelines. The repeated mechanical stress causes stresses to build up in the material, which can lead to microcracks and weakening of the surface. At the same time, the presence of corrosive media such as moisture, salt solutions or aggressive chemicals can increase the corrosion rate of the material. These chemical reactions can accelerate crack propagation and further compromise the structural integrity of the component.

The combination of mechanical stress and corrosion makes vibration corrosion cracking particularly dangerous, as it often goes unnoticed until significant structural damage has already developed. It is therefore important to take appropriate preventative and monitoring measures to minimize the risk of vibration corrosion cracking.

Prevention measures include the use of corrosion-resistant materials, optimization of design parameters to reduce stress concentrations, application of protective surface coatings and regular inspection and maintenance of components to detect potential damage at an early stage. Overall, vibration corrosion cracking is a complex and serious form of corrosion that requires careful planning, monitoring and maintenance to ensure the safety and reliability of metallic structures.
