The Department of Materials and Process Applications for Complete Vehicles deals with the topic of corrosion protection for automotive and rail vehicle construction. Especially at the joints of vehicle structures in multi-material design, the prevention of contact, crevice and stress corrosion cracking poses a particular challenge.

In order to characterise the susceptibility of a material combination of the most important lightweight structural materials (steel, aluminium, magnesium and CFRP/GRP) to contact corrosion and to evaluate the protective effect of coatings, a large number of different test standards are available. The Institute of Vehicle Concepts has a new universal corrosion testing device for salt spray, condensation water and climate change tests.

In addition, effects such as infiltration or filiform corrosion can also be detected under reproducible conditions with the aid of the extended temperature range, and in only a fraction of the test time compared to outdoor weathering.
