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).

Im Laufe des Betriebs von Hochdruck - und Hochtemperatur einrichtungen sind Hartmetall - und Stahlmatrizen einem Erosionsverschleiß bei der Synthese von Diamanten und anderen überharten Stoffen ausgesetzt, was zur Arbeitsraumveränderung und Lebensdauerveminderung der Einrichtung führt. In the course of the operation of high pressure and high temperature equipment hard metal and steel matrices are subject to erosion during the synthesis of Exposed to diamonds and other over-hard materials, which changes the working space and reduction in the service life of the facility.
In der Hochdruck - und Hochtemperatureinrichtung ändert sich als Folge daraus die Größe des zu erzeugenden Druckes bei ein und derselben Preßkraft,wodurch Parameter (Druck und Temperatur) bei der Synthese von Diamanten und anderen über -harten Stoffen gestört werden. In the high pressure and high temperature equipment changes as The consequence of this is the magnitude of the pressure to be generated with one and the same pressing force, as a result of which Parameters (pressure and temperature) in the synthesis of diamonds and others about - hard materials are disturbed.
In Fig. 1 ist eine der mit Stahlringen 2 verbundenen Matrize 1 gezeigt, un welcher sich Erosionsverschleiß 3 aus -gebildet hat. In Fig. 1 one of the die 1 connected to steel rings 2 is shown, and which erosion wear 3 has formed.
In Fig. 2 ist dieselbe Matrize nach der Verschleißbe -Seitigung dargestellt. Man füllt die gebildete Erosionsbeschädigung 3 mit Pulver eines hochschmelzenden Metalls aus der Gruppe,bestehend aus Nickel, Eisen, Kobalt, Mangan, Molybdän, Titan, Tantal, Wolfram, Chrom, Niobium, Rnenium, wobei diese Metalls einzeln oder gemeinsam genommen werden, und unterwirft sie einer Einwirkung von Hochdruck und Hochtemperatur un -mittelbar im Laufe der Synthese von Diamanten und anderen u0erhaten Stoffen. Unter Einwirkung von hohem Druck und Temperaturen werden die hochschmelzenden Metallpulver mit dem Teil verschweißt. In Fig. 2 the same die is shown after wear elimination. The erosion damage 3 formed is filled with powder of a high-melting point Metal from the group consisting of nickel, iron, cobalt, manganese, molybdenum, titanium, Tantalum, tungsten, chromium, niobium, rnenium, these metals individually or together and subjects them to high pressure and high temperature immediately in the course of the synthesis of diamonds and other materials. Under the action of high pressure and Temperatures will be the high melting ones Metal powder welded to the part.
