Aluminium-Silizium-Legierungen für Kolben und Zylinder von Motoren.
Für Gusszwecke sind binäre Aluminiumlegierungen mit hohem Siliziumgehalt allgemein bekannt.
Ferner sind Mehrstofflegierungen mit andern Zusätzen, wie Mangan, Kobalt u. dgl., die mehr als 2%

und Wirtschaftlichkeit betrifft, dar. Vielfach ist die eine der Eigenschaften auf Kosten der andern hochgezüchtet, ohne ein allseitig befriedigendes praktisches Ergebnis zu erzielen. So wurden Legierungen mit hohen Härten, die bis zu 200 kg ! mm2 betrugen, vorgeschlagen, die jedoch durch eine sehr schlechte Bearbeitbarkeit, durch hohe Reibungswerte der Legierung im Zylinder und einem zunehmenden Ausdehnungskoeffizienten erkauft werden mussten.
Durch vorliegende Erfindung wird bezweckt, jede der bekannten Eigenschaften, die für ein ein- wandfreies Arbeiten der Leichtmetallkolben erforderlich sind, auf ein Höchstmass zu steigern. Es wurde gefunden, dass Aluminium-Silizium-Legierungen mit 5-25% Silizium, denen eines oder mehrere der nachstehenden Elemente einzeln oder zu mehreren in Mengen bis zu 10% zugesetzt werden, diese Eigenschaften in erhöhtem Masse aufweisen. Als Zusatzelemente kommen folgende in Frage'Tellur, Strontium und Lanthan. Ferner können zu diesen Elementen noch Magnesium, Kupfer, Eisen, Mangan, Nickel, Kobalt, Chrom und Lithium in Mengen bis zu je 2% hinzulegiert werden.
Durch die genannten Zusätze wird erreicht, dass die guten Eigenschaften der Kolben, im besonderen die Härte, Warmhärte, Bearbeitbarkeit, Ausdehnung, Gleitfähigkeit, Abnützung, Wärmeleitfähigkeit und die Wirtschaftlichkeit in ein durchaus harmonisches Verhältnis zueinander gebracht werden können und im Endergebnis ein Höchstmass an Leistungen und Wirtschaftlichkeit darstellen.

Aluminum-silicon alloys for pistons and cylinders in engines.
For casting purposes, binary aluminum alloys with a high silicon content are well known.
Furthermore, multicomponent alloys with other additives, such as manganese, cobalt and the like. the like that are more than 2%
EMI1.1
and economy concerns. In many cases, one of the properties is bred at the expense of the other, without achieving a practical result that is entirely satisfactory. Alloys with high hardnesses up to 200 kg! mm2 were proposed, but had to be bought at the expense of very poor machinability, high friction values of the alloy in the cylinder and an increasing coefficient of expansion.
The aim of the present invention is to maximize each of the known properties which are required for the light metal pistons to work properly. It has been found that aluminum-silicon alloys with 5-25% silicon, to which one or more of the following elements are added individually or in quantities of up to 10%, have these properties to an increased extent. The following additional elements can be used: tellurium, strontium and lanthanum. Magnesium, copper, iron, manganese, nickel, cobalt, chromium and lithium can also be added to these elements in amounts of up to 2% each.
The above-mentioned additives ensure that the good properties of the pistons, in particular the hardness, hot hardness, machinability, expansion, sliding ability, wear, thermal conductivity and economic efficiency can be brought into a perfectly harmonious relationship and, in the end, a maximum of performance and Represent profitability.
