Definitions
- the invention relates to a method for the near-net-shape production of components or semi-finished products made of hard-to-cut light metal alloys and one made by the process Component or semi-finished product.
- powder-metallurgical manufacturing is highly wear-resistant Components of the material delivered as powder, processed in the classic powder press process, sintered, heat treated and calibrated.
- the peculiarity of such a highly wear-resistant the material is very distorted during sintering due to the necessary liquid phase sintering is caused.
- the required dimensional and dimensional accuracy in the subsequent Calibration is restricted here.
- the invention can also be referred to are used as a method for producing a sintered part from sintered light metal with variable Proportions of wear protection particles as an alloy component.
- this is a method for producing Sintered molded parts made of light metals, preferably aluminum with 10 - 30% silicon content, Mg 0-3%, Cu 0-5%, Zn and Fe 0-7%.
- Other light metals with changed Si components can be produced in this way.
- hard material particle additives can also be used such as oxides, carbides and silicates with proportions of 0-30%.
- the process advantageously combines the processes of cold or hot isostatic presses, Extrusion, sawing and calibration with preferably integrated faceting, if necessary Heat treatment and forging into a new whole.
- the starting point of the invention is the powder metallurgical material Aluminum with Si fractions of approx. 14% which, among other things, is used in an application Sprocket against a steel chain, as a rotor and stator in a camshaft phasing system or an oil pump has excellent, previously unknown, good wear properties.
- the precision that is customary in sintered parts is generated.
- the big delays like in the classic sintering process described above no longer occur here.
- the highly wear-resistant Material can be manufactured within narrow dimensional tolerances.

Abstract
Description
- Verpressen des Rohpulvers in einer Kalt- oder Heißisostatpresse zu einem Bolzen oder einer Form, die zum späteren Strangpressen geeignet ist. Vorteilhaft ist hier der Einsatz eines gepressten Bolzens aus Leichtmetallpulver, um im Gegensatz zu schmelzmetallurgisch hergestellten Bolzen ein gleichmäßigeres Gefüge ohne Lunker und Seigerungen etc. (mit gleichmäßig guter Si-Verteilung und damit guten Verschleißeigenschaften) zu erhalten;
- Strangpressen des Bolzens nahe der Sintertemperatur des Leichtmetalls. Dabei Rekristallisation des Gefüges und Temperaturerhöhung bis zur optimalen Temperatur. Der Strangpressbolzen hat nun schon eine sehr gute Maßtoleranz, die für manche Bauteile schon genügen kann;
- wenn die Maßtoleranz noch nicht ausreichend ist, um hochpräzise, einbaufertige Konturen zu erhalten, wird der stranggepresste Bolzen noch weiter nachkalibriert;
- der Strangpressbolzen wird in das für das Bauteil später notwendige Maß in geeigneter Weise getrennt. Gegebenenfalls wird er dann noch warmbehandelt, einem Nachkalibrierarbeitsgang unterzogen und an definierten Kanten facettiert. Denkbar ist auch, den Strang als Ganzes in einer Art Ziehprozess auf genaue Maße zu bringen und danach zu trennen.
