Implementation of EIS Test Routines into Industrial Application
Abstract
Aluminium and steel are base materials in metal packaging. Beside some chemical or physical surface treatments several steps of surface finishing are involved to enhance the interaction stability of the plain metal surfaces mainly by organic coatings as lacquers or laminates. Since 1988 the Fraunhofer Institute of Process Engineering and Packaging (FhIVV) at Freising, Germany, and different industrial working groups of the Industrial Association of Food Technology and Packaging (IVLV), Munich, Germany, forced the application of EIS-methods in material testing within research and development of the packaging industry. Application fields are the matallic or metaloxidic surfaces, the surface treatments and the layer conversion or layer formation processes, the coated metals with lacquers, primers, adhesives, laminated or coextruded films. The interest in surface properties ranges from surface reactivities, corrosion resistances, inhibition and passivation of the metal up to the interaction stability, porosity and adhesion of the coated systems.
