Thermally sprayed bearing layer, which is made of copper alloy and is built with a filler material dispersed in the copper alloy, for a connecting-rod eye of a connecting rod

摘要

The thermally sprayed bearing layer (GS), which is made of copper alloy (E) and is built with a filler material (F) (2-60 wt.%) dispersed in the copper alloy, for a connecting-rod eye of a connecting rod, is claimed. The filler material is made of aluminum oxide powder, and has a maximum grain size of 50 mu m. The bearing layer has a gradient of aluminum oxide content, which decreases from the base of the thermally sprayed bearing layer to a surface. An independent claim is included for a method for producing a thermally sprayed bearing layer for a connecting-rod eye of a connecting rod.
