MULTILAYER COATING FOR METAL-CUTTING TOOL

A multilayer coating for a metal-cutting tool consists of alternating layers of two components, one of them being the nitride or carbide of a metal of the group IV and the other being the nitride or carbide or boride or silicide of a metal of the group VI. The thickness of the layer of compound of t...

Beschreibung
Zusammenfassung:	A multilayer coating for a metal-cutting tool consists of alternating layers of two components, one of them being the nitride or carbide of a metal of the group IV and the other being the nitride or carbide or boride or silicide of a metal of the group VI. The thickness of the layer of compound of the metal of the group IV equals to 0.05-0.5 $g(m) whereas the thickness of the layer of compound of the metal of the group VI equals to 15-40 per cent of the thickness of the layer of compound of the metal of the group IV. The multilayer coating is intended preferably for applying on metal-cutting tools used for machining high-alloy materials. Un revetement multi-couches pour un outil de coupe de metaux comprend des couches alternees de deux composants, l'un d'eux etant le nitrure ou le carbure d'un metal du groupe IV et l'autre etant le nitrure ou le carbure ou le borure ou le siliciure d'un metal du groupe VI. L'epaisseur de la couche du compose du metal du groupe IV est egal a 0,05-0,5 (Alpha) tandis que l'epaisseur de la couche du compose de metal du groupe VI est egale a 15-40% de l'epaisseur de la couche du compose de metal du groupe IV. Le revetement multicouche est destine de preference a l'application sur des outils de coupe de metaux utilises pour l'usinage de materiaux hautement allies.
