Description

Verwendung von Kupfer-Aluminium-Legierungen für Kolben Die Erfindung bezieht sich auf die Verwendung einer Legierung aus Kupfer, 83 %, Aluminium, I o 0;o, Eisen, 4. %, Nickel, 10;ö, Mangan, 20,ö, zur Herstellung von Kolben für Verbrennungskraftmaschinen. Kupfer-Aluminium-Legierungen hat man bereits für .andere Zwecke verwendet, z. B. für die Herstellung von Torpedos und Maschinen, wie Dynamos und Turbinen usw. Die erfindungsgemäße Verwendung dieser Legierung zur Herstellung von Kolben bietet zahlreiche Vorteile, Das solchen Kolben innewohnende große Wärmeleitungsvermögen beseitigt örtliche Erwärmung und deren übelstände, wie beispielsweise selbsttätige Zündung usw. Sie sind im erwärmten Zustande unoxydierbar, die Ablagerung von Galmei wird in beträchtlichem Ausmaße vermindert, und die trotzdem auftretendenAblagerungen sind leicht :entfernbar. Außerdem behalten diese Kolben bei ihrer Verwendungstemperatur ihre mechanischen Haupteigenschaften : Elastizität, Festigkeit, Härte (welche einen besseren Sitz der Kolbenringe sichert), geringerer Reibungskoeffizient, Beseitigung der Gefahren der Korrosion und des Werkstoffverlustes. Es ist ferner im Hinblick auf die Schwundverminderung leicht, diese Kolben einer Wärmebehandlung zu unterwerfen.Use of copper-aluminum alloys for pistons The invention refers to the use of an alloy of copper, 83%, aluminum, I o 0; o, iron, 4.%, nickel, 10; ö, manganese, 20, ö, for the manufacture of pistons for internal combustion engines. Copper-aluminum alloys have already been used for other purposes, e.g. B. for the manufacture of torpedoes and machines, such as dynamos and turbines, etc. The The use according to the invention of this alloy for the production of pistons offers numerous Advantages, That eliminates the inherent high thermal conductivity of such pistons Local heating and its evils, such as automatic ignition etc. They are non-oxidizable when warmed, the deposit of calamine becomes reduced to a considerable extent, and the deposits which nevertheless occur are easy: removable. In addition, these pistons maintain their temperature of use their main mechanical properties: elasticity, strength, hardness (which one ensures better fit of the piston rings), lower coefficient of friction, elimination the dangers of corrosion and loss of material. It is also in view To reduce shrinkage, it is easy to subject these pistons to a heat treatment.
