Described is a process for producing a sliding bearing with a copper-based Babbit metal lining (1) that has at least 10 wt % softer metal intercalations (3) in a copper or copper-alloy matrix (2) and with a tin-containing, preferably aluminum-based working surface (7), with first a diffusion barrier layer (6) being deposited on the Babbit metal lining and then the working surface being physically deposited in a vacuum on the diffusion barrier layer. To ensure advantageous working properties the invention proposes that prior to deposition of the diffusion barrier layer the surface of the Babbit metal lining receiving the diffusion barrier layer is subjected to a chemical etching process until this produces in the region of the softer intercalations (3) depressions in the surface of the copper or copper-alloy matrix (2) to a depth of at least one tenth of the thickness of the working surface (7) deposited afterward, but at least 2 mu m. |
