Abstract

Druckinfiltrierter Formkörper, bestehend aus mindestens 23% einer Aluminiumlegierung und mindestens 2% Graphit und Keramikpartikeln bis zu dessen maximaler SchüttungPressure-infiltrated molded body, consisting of at least 23% of an aluminum alloy and at least 2% graphite and ceramic particles up to its maximum bulk

Description

Die nachfolgende Erfindung betrifft einen kostengünstigen Formkörper aus keramikpartikelverstärktem Aluminium unter Zusatz von Festschmierstoffen vorzugsweise Graphit, hergestellt durch die Squeeze-Casting-Technologie.The following invention relates to a low-cost molded article of ceramic-particle-reinforced aluminum with the addition of solid lubricants, preferably graphite, produced by the squeeze casting technology.

In der Gebrauchsmusterschrift DE 200 03 776 wird ein Formkörper mit einem Anteil von Nanofeinpartikeln aus Keramik beschrieben, dessen Grundwerkstoff ein Metall (z. B. Aluminium) ist. Er enthalt explizit keinen Graphit und wird über Sintern hergestellt.In the utility model DE 200 03 776 describes a shaped body with a proportion of ceramic nanofine particles whose base material is a metal (eg aluminum). It explicitly contains no graphite and is produced via sintering.

In der Offenlegungsschrift DE 10 2009 002 425 wird u. a. ein Lagerelement aus Eltimid beschrieben, wo ein Graphitanteil von bis zu 15% enthalten ist und der mittels Druckguß hergestellt wird. Allerdings ist hier der Basiswerkstoff Polyamid.In the published patent application DE 10 2009 002 425 inter alia, a bearing element made of Eltimid is described, where a graphite content of up to 15% is contained and which is produced by die casting. However, here is the base material polyamide.

In der vorgelegten Erfindung werden Keramikpartikel und ein Festschmierstoff homogen vermischt und mit einer Aluminiumlegierung druckinfiltriert. Dabei wird eine Pre-Form (Schüttung einer Mischung von keramischen Partikeln und mindestens einem Festschmierstoff von geeigneter Form und Größe) nach dem Squeeze-Casting-Verfahren infiltriert.In the present invention, ceramic particles and a solid lubricant are homogeneously mixed and pressure infiltrated with an aluminum alloy. In this case, a preform (bed of a mixture of ceramic particles and at least one solid lubricant of suitable shape and size) is infiltrated by the squeeze-casting method.

Die Matrix des Formkörpers besteht dabei aus:

  • – 23 bis 70 Vol-% einer Aluminiumlegierung, vorzugsweise AlMg5Si2Mn
  • – 30 bis 75 Vol-% von Keramikpartikel, vorzugsweise Siliziumkarbid
  • – mind. 2 Vol-% eines Festschmierstoff, vorzugsweise Graphit.
The matrix of the shaped body consists of:
  • - 23 to 70% by volume of an aluminum alloy, preferably AlMg5Si2Mn
  • - 30 to 75 vol% of ceramic particles, preferably silicon carbide
  • - At least 2% by volume of a solid lubricant, preferably graphite.

Der beschriebene Formkörper eignet sich als Lagerwerkstoff mit sehr guten Not- und Trockenlaufeigenschaften, der sich durch Verschleißfestigkeit, einer sehr niedrige Reibungszahl und hoher Druckfestigkeit auszeichnet sowie selbstschmierend ist.The shaped body described is suitable as a bearing material with very good emergency and dry running properties, which is characterized by wear resistance, a very low coefficient of friction and high compressive strength and is self-lubricating.
