CONCAVE SLIDING ELEMENT AND PRODUCTION PROCESS THEREFOR

摘要

According to the invention, a system of layers is applied to a substrate (1) such that an intermediate layer (2) is covered by a diffusion layer (3) which is covered by a slide layer (4). At least the slide layer is applied by electron beam vaporization. The variation in layer thickness is less than 15 %, at least in an angular range of +/- 70 DEG with respect to the crown region (5) of the substrate. These sliding elements are used as heavy-duty bearings or bearing shells, preferably in internal combustion engines.
