Definitions
- US 4,447,263 discloses inserts of a titanium based carbonitride alloy provided with a wear resistant surface layer of carbonitride or oxycarbonitride alone or in combination where the surface layer is completely free from binder phase.
- the layer is obtained by a heat treatment at 1100 - 1350°C in an atmosphere of N2 , CO and/or CO2 at subpressure.
- the nitrogen content increases towards the surface. This enrichment is mainly due to the presence of TiN grains formed during heat treatment and can be identified by X-ray diffraction. These TiN grains may grow separately but can also grow epitaxially, forming an outer shell at least partly surrounding carbonitride grains. Furthermore, the nitrogen enriched zone has a binder phase content being approximately the same as in the bulk and being distributed all the way out to the surface.
- a powder mixture with a chemical composition of (at%) 40.7% Ti, 3.6% W, 30.4% C 13.9% N and 11.4% Co was manufactured from Ti(C,N), WC and Co raw material powders.
- the mean grain size of the Ti(C,N) and WC powders were 1.4 ⁇ m.
- the powder mixture was wet milled, dried and pressed into green bodies of the insert type TNMG 160408-PF. The bodies were liquid phase sintered at 1430 °C for 90 minutes in a 10 mbar Ar atmosphere.
