Verwendung von FeC-Legierung zur Erneuerung der Oberfläche von Zylinderlaufbuchsen

摘要

The present invention relates to a cylinder liner made from gray cast iron, an aluminum material or a ceramic material for an engine block for an internal combustion engine. According to the invention, it is provided that the cylinder liner has a thermally sprayed layer of a low-alloy iron alloy or a bonding layer, which consists of a nickel-aluminum alloy made up of 80 to 95% by weight of nickel and 5 to 20% by weight of aluminum, on its worn running surface, and has a layer serving as a tribological running surface on top of the bonding layer. The present invention also relates to a method for producing a cylinder liner of this type and to a composite part made up of an engine block for an internal combustion engine and at least one cylinder liner of this type. The invention allows the inexpensive repair of worn cylinder liners without the need to adapt new pistons.
