Definitions
- the invention relates to a hard metal or cermet cutting material for machining chrome-containing metal workpieces, such as e.g. Austenites, Ni-based alloys, stones or steels, with a hard material phase containing carbides, nitrides and / or carbonitrides and a 3 to 25 mass% binder phase made of iron, cobalt and nickel.
- chrome-containing metal workpieces such as e.g. Austenites, Ni-based alloys, stones or steels
- a hard material phase containing carbides, nitrides and / or carbonitrides and a 3 to 25 mass% binder phase made of iron, cobalt and nickel.
- the invention further relates to a use of the hard metal or cermet cutting material for machining metal workpieces.
- the binder In hard metals such as cermets, the binder is used to form a liquid phase at sintering temperature, which is in equilibrium with the hard material phase and can wet it.
- the liquid binding phase is said to have considerable solubility for the hard material phase with the sintering temperature, but is said to be eliminated again on cooling. Reactions of the binder phase with the hard material phase, which lead to the consumption or 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 temperatures prevailing here in such a way that the binder leads to the hardest and toughest cohesion of the hard metal or cermet body.
- the 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, where the sum of the metals Co, Ni, Cr and Fe does not exceed 100%.
- the binder phase can additionally contain up to 5% by mass of V, Mo and / or Al, up to the solubility limit Ti, W, Ta / Nb, Zr and / or Hf and up to 15% by mass of Mn. Oxygen, nitrogen and / or boron can furthermore be present in the binder to the maximum solubility.
- the carbon content in the cutting material is adjusted so that there is no ⁇ and no C porosity.
- the binder phase preferably has no hexagonal components.
- the hard metal or cermet body is based on the inventive core idea that there is no difference or only the smallest possible difference in the concentrations of the lying components between workpiece and tool between the metal to be machined and the cutting material. This is intended to minimize interdiffusion of the cobalt from the hard metal or cermet cutting material on the one hand and the alloy elements of the steel on the other hand during machining.
- the binding phase of the cutting material must also contain chromium in addition to iron, nickel and cobalt, whereby good wettability of nickel and cobalt is the reason for the minimum 10 and maximum 75% content in the binder phase.
- the rest iron and nickel with at least 4% by weight, but not more than 36% by weight nickel or iron , the ratio Ni / Fe should be between 1.5: 1 to 1: 1.5 is inevitably contained in the binder in the present material for machining Cr.
- an fcc structure is formed in the binder described.
- the tendency of the cutting material to stick can only be avoided if there is significant Cr content in the binder.
