Der Nachteil der betrachteten Einrichtung besteht darin, daß in Hartmetallmatrizen zylindrische mit einem Wärmedämm -stoff ausgefullte Vertiefungen vorhanden sind.Der Winkel zwischen Boden und Wand einer solchen Vertiefung bildet eine Spannungskonzentrationsstelle und setzt deshalb die Festig -keit und somit die Lebensdauer der Matrize herab. The disadvantage of the device under consideration is that in hard metal matrices cylindrical recesses filled with a thermal insulation material are present The angle between the bottom and the wall of such a depression forms a stress concentration point and therefore reduces the strength and thus the service life of the die.

Einen weiteren Nachteil dieser Einrichtung stellt die Notwendigkeit dar, eine spezielle stromleitende Scheibe zu verwenden,um einen Stromkreis zwischen Matrize in der Hoch -druckeinrichtung und Reaktionsgefäß zu bilden.' Im Zusammen -hang damit werden mehrere Einrichtungen ohne zylindrische, zum Füllen mit einem Wärmedämmstoff dienende Vertiefung aus -geftihrt (USA - Patentschrift Nr. 2941244). Another disadvantage of this device is the necessity represent to use a special electroconductive washer to create a circuit between Form die in the high-pressure device and reaction vessel. ' Together -hang so that several bodies without cylindrical, for filling with one Thermal insulation material recess from -geftihrt (USA - Patent No. 2941244).

Es ist bei diesen Einrichtungen von besonderer Wichtig keit,ErosionsSchäden zu beseitigen. It is particularly important in these facilities to prevent erosion damage to eliminate.

Zweck der vorliegenden Erfindung ist derSdie genannten Nachteile su vermeiden. The purpose of the present invention is to address the disadvantages mentioned avoid su.

Gemäß dem Gesagten wurde eine Aufgabe gestellt, ein Ver -fahren zur Beseitigung von Erosions'schäden an Ober -flachen von Hartmetall - oder Stahlteilen unmittelbar im Laufe der Synthese, d.h. ohne deren Versand in die Werkzeug -macherei, zu entwickeln. According to what has been said, a task was set, a method for Removal of erosion damage on the surfaces of hard metal or steel parts directly in the course of the synthesis, i.e. without sending it to the tool shop, to develop.
