FIELD: metallurgy. ^ SUBSTANCE: invention relates to instrument or item which allows coating. Cutting tool with coating which contains main part from in essence not containing carbon, heat-treatable alloy on the basis of iron of system iron-cobalt-molybdenum/ tungsten-nitrogen and coating, applied by method PVD or CVD and allowing one-phase crystalline structure with cubical face-centered lattice. ^ EFFECT: obtaining tool with cutting part keeping equal cutting properties during cutting and allowing high thermal conduction that provides increasing of tool durability. ^ 12 cl, 5 dwg |
