Cylinder crankcase is formed as a cast part made from a super-eutectic aluminum alloy having the composition AlSi17Cu4Mg containing 0.1-2.0 wt.% nickel and 0.3 wt.% iron so that a further wear-resistant phase in the form of nickel-copper aluminides is pres...

The cylinder running surface of a light metal alloy has a defined grip fitting structure at an uncoated cylinder running surface, where a wear layer can be bonded. The grip fitting structure (2) lies on the radial direction of the running surface. The coat...
