To enhance the resistance of dies employing by EMB to wear and impact an innovative concept concerning the die surface modification was developed. Different PVD multilayer systems were deposited, in which the hardness and toughness of the layers were designed related to the soft aluminium sheets and high forming velocity. Corresponding metallographic and mechanical investigations of the multilayers help to understand the relation between microstructure and tribological properties.
