Abstract

Die Erfindung betrifft ein Verfahren zum Herstellen einer Zylinderlaufbuchse aus übereutektischer Aluminium-Silizium-Legierung, die beim Gießen eines Zylinderblocks aus Leichtmetalllegierung miteingegossen wird; um das Verfahren einfacher und kostengünstiger durchführen zu können als dies bislang der Fall ist, wird vorgeschlagen, dass zunächst ein rohrförmiger Körper aus der übereutektischen Aluminium-Silizium-Legierung gegossen wird und dass dieser rohrförmige Körper anschließend spanlos bei Temperaturen zwischen 380 und 515 °C in einem Drückwalzverfahren verformt wird.

Figure 00000001
The invention relates to a method for producing a cylinder liner made of hypereutectic aluminum-silicon alloy, which is cast in during the casting of a cylinder block made of light metal alloy; In order to be able to carry out the method more easily and cost-effectively than has been the case hitherto, it is proposed that a tubular body is first cast from the hypereutectic aluminum-silicon alloy and that this tubular body is then machined at temperatures between 380 and 515 ° C. is subjected to a pressure rolling process.
