The invention relates to a method for preparing metal workpieces for cold forming by applying a lubricant layer (=coating) either to a metal surface or to a metal surface which has been pre- coated with e.g. a conversion coating. The lubricant layer is formed by contacting the surface with an aqueous lubricant composition which has a content in at least two waxes having distinct properties and a content in organic polymer material, the organic polymer material used predominantly being monomers, oligomers, co-oligomers, polymers or/and copolymers based on ionomer, acrylic acid/methacrylic acid, epoxide, ethylene, polyamide, propylene, styrene, urethane, the ester(s) or/and salt(s) thereof. The invention also relates to the corresponding lubricant composition, to the lubricant layer produced thereof and to its use.

L'invention concerne un procédé de préparation de pièces métalliques au formage à froid par l'application d'une couche de lubrifiant (= couche de couverture) soit sur une surface métallique, soit sur une surface métallique préenduite, par ex. d'une couche de conversion, la couche de lubrifiant étant formée par mise en contact de la surface avec une composition de lubrifiant aqueuse qui contient au moins deux cires à propriétés nettement différenciées, ainsi qu'un matériau polymère organique, le matériau polymère organique utilisé étant principalement des monomères, oligomères, co-oligomères, polymères et/ou copolymères à base d'un ionomère, acide acrylique/méthacrylique, époxy, éthylène, polyamide, propylène, styrène, uréthane, leur(s) ester(s) et/ou leur(s) sel(s). L'invention porte également sur la composition de lubrifiant correspondante, la couche de lubrifiant en étant formée et son utilisation.
