It was the aim of this project to investigate new zinc alloy coatings on steel sheet obtained by means of galvannealing steel sheet with metallic pre-coatings. The investigations focused on three 'model-systems' (pre-coatings with Ni, Mn and Fe obtained either by electrolytical deposition (Ni, F...
L'évolution des techniques de construction dans l'industrie automobile se traduit par l'utilisation croissante des tôles revêtues, dont certaines sont assemblées par soudage à l'arc sous protection gazeuse au moyen d'équipements robotisés. Les principales difficultés rencontrées concernent le ta...
A system for the preparation and decoating of organic coated/galvanised scrap has been developed. Scrap preparation via a shrear shedder was found to yield an open-faced feedstock which was suitable for the subsequent wet chemical decoating stage (acidic and caustic media). A number of environme...
