Abstract

A plain bearing having a bearing gap filled with liquid metal has two plain bearing parts each having a surface contiguous to the liquid metal, these surfaces delimiting a gap connecting the bearing gap with the surrounding space. At least one of the surfaces is provided, in its area contiguous to the liquid metal, with a layer of a material that is effective as a wetting agent for the liquid metal.
