ABSTRACT:
Bearing shell of a connecting rod which is located in the larger connecting rod eye in which the bearing shell is constituted by several thermally sprayed layers and the topmost material layer of the bearing shell is essentially constituted by an aluminum/bismuth alloy as well as a bearing shell of a connecting rod which is at least located in the larger connecting rod eye in which the entire bearing shell is essentially constituted by a thermally sprayed layer of aluminum/bismuth alloy and process for the fabrication of a bearing shell on a connecting rod eye with the steps mechanical roughening of the connecting rod surface in the region of the bearing, thermal coating onto the surface with a bearing metal or a bearing material to build up a bearing layer and thermal coating onto the bearing layer with an Al/Bi alloy to build up a sliding layer, as well as a process for the fabrication of a bearing shell on a connecting rod eye with the steps mechanical roughening of the connecting rod surface in the region of the bearing and thermal coating onto the surface with an Al/Bi alloy to build up a bearing and sliding layer.
