Metallic components are exposed mainly to corrosive influences during operation. The damaging influence of corrosion on the fatigue strength of these components is great and widely known. Corrosion processes (on top of the mechanical load) initiate and promote material fatigue. Whereas as the mechanical vibration loads and their effects on the fatigue strength of components can be determined in calculations and experiments, it is essential to have experimental verification of the corrosion load because of the great variety of influencing factors.
Therefore industrial materials are usually tested for corrosion resistance using salt fog and salt spray tests. The tests are based on common standards including DIN EN ISO 9227, DIN EN ISO 6270-2, DIN EN 60068-2, and DIN EN ISO 7253, DIN EN ISO 4628 as well as various manufacturers' specifications.
IABG has a number of different mobile and stationary facilities for running fatigue strength tests under the influence of corrosion.
