Abstract (en)
[origin: WO2015074775A1] There are known methods for producing a cylinder running surface of a cylinder crankcase of an internal combustion engine in which a coating (30) is produced on a cylinder inner wall (24) of a cast cylinder crankcase by thermal spraying, and wherein an inert gas is used as the atomizer gas. However, the layers created are often susceptible to corrosion. In order to prevent this, it is proposed that the mass throughput of the coating material (15) in the thermal spraying is 8 to 22.5 kg/h. This provides a cylinder crankcase for an internal combustion engine with a cylinder running surface in which the sprayed-on coating (30) has a layer porosity of 4.5 to 25% and an oxide content of 0.5 to 5%. This coating has a high corrosion resistance.
