From the beginning of the development of a defined Automotive Materials Technology it has been characterised by environment-materials-energy features.

After the environmental issue in the sixties (increased atmospheric and road reactivity), the energy issue in the seventies (the debate on the limited resources of energy-holding raw materials), the lifetime issue in the eighties (demonstrated by a strong increase in quantity and type of precoated products), the environmental issue (now favouring the light-weight concept and product recyclability) is rising again.

To realise automotive corrosion control in an environment of increasing reactivity, a number of product and process developments have been realised.

A general automotive corrosion control strategy can be defined based on developments in the postfinishing and prefinishing route. Elucidation of corrosion mechanisms as a basis for realistic accelerated laboratory tests is a prerequisite for future automotive corrosion control, especially in a light-weight materials concept.
