Abstract
The invention relates to a sliding bearing (1) comprising a support element (2) on which at least one additional functional layer (3) is arranged which consists of a silver-based alloy with silver as the main constituent of the alloy. The functional layer (3) contains, in addition to silver, at least one element from a group including gallium, manganese, nickel, copper, zinc, germanium, indium, tin, antimony and aluminum, wherein the total content of said elements is between 0.01 wt. % and 70 wt. % and the remainder is formed by silver containing production-related impurities, with the proviso that the proportion of each of the elements gallium, manganese, nickel, zinc, germanium and antimony in the binary silver-based alloys is a maximum of 49 wt. %, the proportion of indium being not more than 10 wt. %, the proportion of tin or copper content in the functional layer embodied as a sliding being not more than 10 wt. % and 14 wt. % respectively.
