Corrosion

Corrosion refers to the reaction of a material under aggressive conditions, leading to changes in the material. Each year corrosion results in high maintenance costs for a variety of structures, bridges, industrial plants, and vehicles. Besides the financial implications, corrosion damage that goes undiscovered poses a significant risk: Advanced corrosion can cause premature failure of components, leading to outages or accidents. Manufacturers and users are thus forced to take appropriate preventative measures. These include:

  • Correct selection of materials
  • Manufacture of suitable corrosion protection systems
  • Determination and optimization of the service life of components
  • Development of suitable monitoring and inspection tools and the corresponding protocols

Corrosion protection using paints and coatings

Paints and coatings are the most common form of corrosion protection. These are employed for the full A to Z of applications. In many areas there is a need for new and more efficient coatings in order to provide components with a longer service life and higher value retention. For heavy-duty corrosion protection, alternative corrosion protection coatings are being actively developed. This is because ever greater restrictions on heavy metal-based corrosion inhibitors and corrosion protection pigments have severely limited the choice of suitable coatings in recent years.

Portfolio of services in the area of corrosion protection at Fraunhofer IFAM
