Abstract
Un film primaire de Ni, Fe, et/ou Co est constitué sur une surface d'aluminium, un film phosphate est ensuite constitué sur cette surface d'aluminium ayant reçu ce film primaire, ou sur une surface d'un composite d'aluminium sur laquelle un film primaire a été constitué, avant d'être combiné à une tôle d'acier enduite à base de zinc. Cette méthode de traitement de surface n'entraîne pas les problèmes de pollution courants par l'ion Cr6+ et par F-, et l'on constate à l'usage une faible dégradation du liquide de traitement servant à réaliser le film phosphate.
