The invention relates to a process for processing hard metal, in particular hard metal scrap, wherein the hard metal is alloyed with a low-melting alloy metal in a reaction space of a reactor (10) with a heat supply, wherein the alloy metal is converted into a vapor phase in the presence of inert gas, and wherein the alloy metal is subsequently at least partially condensed in a condensation step, and wherein an overpressure relative to ambient pressure is present in the reaction space at least during the condensation phase. According to the invention, provision is made in particular for the inert gas to be permanently supplied to the reaction chamber at least temporarily during the condensation phase from an inert gas source (60) disposed outside of the reaction chamber via an inert gas supply line (61), and for the inert gas to be discharged from of the condenser (30) into the environment at least at certain intervals during the condensation phase.

Incorporating wear protection element receptacles on the bottom side and designing the wear protection elements (20) as pins achieves a simple design, low production costs, and high wear resistance.
The invention relates to a stripping solution (14), to a method (41), and to a device (10) for a wet chemical removal of a PVD or CVD titanium nitride layer from a hard metal support element using such a solution (14).

The invention relates to a method for processing hard metal, more particularly hard metal scrap, wherein: - the hard metal is alloyed with a low-melting alloying metal in a reaction chamber of a reactor (10) while heat is applied; - the alloying metal is then converted into a vapor phase in the presence of inert gas; - subsequently the alloying metal is at least partially condensed in a condensation step; and - in the reaction chamber, there is a positive pressure with respect to ambient pressure at least during the condensation phase. More particularly, according to the invention, the inert gas is continuously supplied to the reaction chamber from an inert gas source (60) outside of the reaction chamber via an inert gas supply line (61) at least temporarily during the condensation phase, and the inert gas is discharged from the condenser (30) into the environment at least in phases during the condensation phase. In this way, the plant complexity can be considerably reduced in comparison with hard-metal decomposition methods known from the prior art.
