Title

Verfahren zur Herstellung gleitflaechenseitig konkav gekruemmter Gleitelemente

Other Title
Concave sliding element for heavy-duty bearing - has layer structure applied to carrier body with at least sliding layer applied via electron beam vapour deposition.
Abstract
The sliding element has a layer structure applied to the surface of a carrier body (1) in a vacuum, to provide an intermediate layer (2) overlaid by a diffusion blocking layer (3), in turn covered by a sliding layer (4). At least the sliding layer is provided via an electron beam vapour deposition process, with a variation in the layer thickness of less than 15% in an angular range of 70 degrees to either side of the crown region (5) of the carrier body. Pref. the sliding layer is formed from a metallic dispersion alloy containing Pb, Cd, Sn, Zn, Ni, or Cu. USE - For heavy-duty bearings in i.c. engine.
