Patent

CA 2588899

The layer structure of a blanking die produced according to a CVD method contains a thick outer covering layer of TM-TiCN, and a multilayer Al2O3 layer arranged beneath the covering layer. Said multilayer Al2O3 layer consists of at least two aluminium oxide layers between which TiCN layers, and optionally TiAlC-NO layers for improving adhesion, are arranged. One such overall design has especially good chip removal properties.

La structure en couches d'une plaque de coupe, fabriquée au moyen d'un procédé de dépôt en phase chimique, contient une épaisse couche de couverture extérieure de TM-TiCN, et une couche multicouche d'Al2O3 située en-dessous de celle-ci. La couche multicouche d'Al2O3 est composée d'au moins deux couches d'oxyde d'aluminium entre lesquelles des couches de TiCN, et éventuellement des couches de TiAlC-NO pour améliorer l'adhérence, sont disposées. Un tel ensemble présente de très bonnes propriétés d'enlèvement de copeaux.
