Description
Verfahren zum Herstellen von Metallkörpern Es ist bekannt, Metalldrähte, insbesondere Stahldrähte, zu spritzen, um besondere Oberflächeneigenschaften oder eine Verstärkung des Grundkörpers zu erzielen. Für das Aufspritzen können nicht nur unlegierte Metalle, sondern auch legierte Stähle und Metallegierungen verwendet werden.Process for the production of metal bodies It is known to use metal wires, in particular steel wires, to be sprayed to obtain special surface properties or to achieve a reinforcement of the base body. For spraying you can't only unalloyed metals, but also alloyed steels and metal alloys are used will.
So wurden auch schon Überzüge aus Hartmetall, das bekanntlich ein makroskopisches homogenes Gefüge haben muß, auf metallischen Grundkörpern durch Aufspritzen hergestellt, wobei die Temperatur des aus Wolframkarbid und einem leichter schmelzbaren Hilfsmetall bestehenden Gemisches so eingestellt wurde, daß der Schmelzpunkt des Wolframkarbides nicht erreicht und somit nur jener Anteil flüssig wird, der dem Bindemittel bzw. dem im Bindemittel gelösten Wolframkarbid entspricht. Es wurde auch schon vorgeschlagen, in Seelen-oder Manteldrähten geringe Mengen von Ferrolegierungen zu verwenden, die beim Schmelzen eine Eisenlegierung bestimmter Zusammensetzung, z. B. Gußeisen, ergeben.This is how coatings made of hard metal, which is known to be a must have a macroscopic homogeneous structure on metallic base bodies Molding made, the temperature of the made of tungsten carbide and a lighter fusible auxiliary metal existing mixture was adjusted so that the melting point of the tungsten carbide is not reached and thus only that portion becomes liquid that corresponds to the binder or the tungsten carbide dissolved in the binder. It was It has also already been proposed to use small amounts of ferro-alloys in core or sheathed wires to use an iron alloy of a certain composition when smelting, z. B. cast iron result.
Alle diese Vorschläge haben zum Ziel, eine Oberfläche oder einen Formkörper mit gleichmäßigem Aufbau herzustellen. In vielen Fällen sind aber besondere technische Werte nur dann zu erzielen, wenn ein oder mehrere Bestandteile im wesentlichen unverändert im gespritzten Teil auftreten.The aim of all of these proposals is to create a surface or a shaped body to be produced with a uniform structure. In many cases, however, they are special technical Values can only be achieved if one or more components are essentially unchanged occur in the molded part.
Die Erfindung betrifft ein Verfahren zum Herstellen von Metallteilen mit ungleichem Gefügeaufbau, bei dem Metalldrähte verspritzt werden, die eine Füllung oder Umhüllung von Zusätzen erhalten, die beim Spritzen nur unvollständig aufgelöst werden. So ist es beim Spritzen von Lagern vorteilhaft, der Seelenmasse grobflockigen Graphit zuzusetzen, wodurch die Gleiteigenschaften verbessert werden. Beim Spritzen verschleißfester Teile sind in der Seele des Drahtes körnige Karbide oder Korund zu verwenden. Ähnliches gilt für die Herstellung von Elektroden und Kontakten, welche neben Kupfer oder Silber ein oder mehrere Elemente mit hohem Schmelzpunkt und/oder mechanischer Festigkeit enthalten. Da die Körnung des zugesetzten Bestandteiles so eingestellt werden muß, daß während des Spritzens kein vollständiges Auflösen eintritt, so können auch im fertigen Spritzteil Legierungselemente vorhanden sein; die sich beim vollständigen Schmelzen gänzlich aufgelöst hätten.The invention relates to a method for manufacturing metal parts with an uneven structure, in which metal wires are sprayed that form a filling or encasing of additives that are only incompletely dissolved when sprayed will. So it is advantageous when spraying bearings, the soul mass to add coarse flaky graphite, whereby the sliding properties are improved. When spraying wear-resistant parts, there are granular carbides in the core of the wire or corundum to be used. The same applies to the manufacture of electrodes and Contacts which, in addition to copper or silver, have one or more elements with a high melting point and / or mechanical strength. Because the grain size of the added ingredient must be adjusted so that it does not completely dissolve during spraying occurs, alloying elements can also be present in the finished molded part; which would have completely dissolved if completely melted.
Gegenüber den bekannten Sinterungsverfahren, welche zu Körpern ähnlichen Aufbaus führen, hat das Verfahren gemäß der Erfindung den Vorteil, daß sich die Formkörper in einfachen und billigen Matrizen herstellen lassen und daß sich die gespritzten Teile durch eine geringe Porosität und eine größere Härte auszeichnen.Compared to the known sintering processes, which are similar to bodies Lead structure, the method according to the invention has the advantage that the Molded bodies can be produced in simple and cheap matrices and that the Injected parts are characterized by low porosity and greater hardness.
