Abstract
NOVELTY - A plain bearing shell (1) has a running-in layer containing a finely dispersed component (7) of concentration continuously decreasing from the shell apex (8) to the edge (9). DETAILED DESCRIPTION - A plain bearing shell (1) has a backing with an electron beam vapor deposited metallic running-in layer containing a finely dispersed component (7) of atomic weight greater than that of the matrix material, the component concentration continuously decreasing from the apex region (8) to the edge region (9). An INDEPENDENT CLAIM is also included for a method of producing the above plain bearing shell, in which coating of the apex region is carried out at a gas pressure of 0.1-5 Pa. Preferred Features: The finely dispersed component is tin, lead, bismuth and/or antimony. USE - Especially as a steel-backed plain bearing shell with an AlSnCu, AlSnPb or AlSnSi running-in layer. ADVANTAGE - The bearing layer exhibits good emergency and running-in properties combined with a high threshold load until the onset of seizure in its heavily loaded region (i.e. the vertex), only contains a high concentration of the relatively expensive finely dispersed component in this region and is simple to produce with uniform thickness over the entire bearing shell by the electron beam vapor deposition process.
