Abstract

Beschrieben wird ein Tablettierwerkzeug, insbesondere Tablettierstempel (1) oder Matritze (1'), mit einem Prägeelement (3; 3'), das zumindest teilweise mit einer zumindest adhäsionsreduzierenden Schicht (5; 5') überzogen ist.A tableting tool is described, in particular a tabletting stamp (1) or die (1 '), with an embossing element (3; 3'), which at least partially with an at least adhesion-reducing layer (5; 5 ') is coated.

Erfindungsgemäß ist vorgesehen, daß zumindest die adhäsionsreduzierende Schicht (5; 5') aus einem Metall oder einem Element der vierten Hauptgruppe des Periodensystems oder aus einer Verbindung mit einem metallischen Bindungscharakter oder aus einer Verbindung mit kovalenten Bindungscharakter oder einer Verbindung mit ionischen Bindungscharakter oder aus einer Sialon-Verbindung oder aus einer Polymer-Verbindung ausgebildet ist, und daß das die Schicht (5; 5') ausgebildetem Material durch eine Kathodenzerstäubung oder durch ein lonenplattieren oder durch ein Aufdampfen oder durch einen CVD-Prozeß oder durch einen PVD-Prozeß oder durch einen PACVD-Prozeß oder galvanisch oder elektrochemisch oder durch ein Plasmaspritzen auf das Tablettierwerkzeug (1; 1') aufgebracht ist.

Figure 00000001
According to the invention, it is provided that at least the adhesion-reducing layer (5; 5 ') consists of a metal or an element of the fourth main group of the periodic table or of a compound with a metallic bond character or from a compound with a covalent bond character or a compound with an ionic bond character or from a Sialon compound or is formed from a polymer compound, and that the material formed by the layer (5; 5 ') by sputtering or by ion plating or by vapor deposition or by a CVD process or by a PVD process or by a PACVD process or galvanically or electrochemically or by plasma spraying onto the tabletting tool (1; 1 ').
