Abstract

Maschinengehäuse (1) aus einer Aluminiumlegierung mit einer Oberfläche aus einer Magnesiumlegierung und mit zumindest einer außen liegenden Struktur (2), insbesondere ein Kurbelgehäuse oder ein Getriebegehäuse für eine Brennkraftmaschine, wobei alle Strukturen (2) in Einbaulage des Maschinengehäuses (1) ausgehend von einem geodätisch höchsten Punkt bezüglich einer Hochachse (A) in zumindest einem Bereich (3) abfallend ausgebildet sind.
Aufgrund der vorgeschlagenen Ausgestaltung des Maschinengehäuses wird eine Korrosion der Oberfläche aus der Magnesiumlegierung weitgehend vermieden bzw. die Bauteillebensdauer erhöht.
