Definitions

  • the invention relates to a cutting tool made of a hard metal or cermet cutting material for machining chromium-containing metal workpieces, such as e.g. Austenitic, Ni-base alloys, stellites or steels, with a carbide, nitrides and / or carbonitride-containing hard material phase and a 3 to 25 mass% binder phase of iron, cobalt and nickel.
  • chromium-containing metal workpieces such as e.g. Austenitic, Ni-base alloys, stellites or steels
  • the invention further relates to a use of this cutting tool for the machining machining of metal workpieces.
  • the binder serves to form a liquid phase at sintering temperature which can be in equilibrium with and wet the hard material phase.
  • the liquid binder phase should have a considerable solubility for the hard material phase with the sintering temperature, but should excrete it on cooling again. Reactions of the binder phase with the hard material phase, which lead to consumption or to the degradation of the binder phase, should be avoided as far as possible.
  • the binder phase should have mechanical properties which correspond to the intended use and the prevailing temperatures in such a way that the binder for a hard and tough as possible cohesion of the hard metal or cermet body leads.
  • the cutting tool made of a hard metal or cermet cutting material has a binder phase with 10 mass% to 75 mass% Co, 10 mass% to 75 mass% Ni, 5 mass% to 30 mass% Cr,> 20 mass% to 60 mass% Fe, wherein the sum of the metals Co, Ni, Cr and Fe does not exceed 100%.
  • the binder phase may additionally contain up to 5 mass% V, Mo and / or Al, up to the solubility limit Ti, W, Ta / Nb, Zr and / or Hf and up to 15 mass% Mn.
  • oxygen, nitrogen and / or boron can be present in the binder to the maximum solubility.
  • the content of carbon in the cutting material is adjusted so that there is no ⁇ and no C porosity.
  • the binder phase has no hexagonal proportions.
  • the cutting core of the inventive core idea that between the metal to be machined and the cutting material with respect to the Cr content no or only the smallest possible difference in the concentrations of recumbent components between the workpiece and tool is present. This is intended to minimize interdiffusion of the cobalt from the hard metal or cermet cutting material on the one hand and the alloying elements of the steel on the other hand during machining.
  • the binder phase of the cutting material in addition to iron, nickel and cobalt must also contain chromium, with a good wettability of nickel and cobalt cause for the at least 10 and a maximum of 75% content in the binder phase.
