A multilayer plain bearing comprises a steel support body, preferably a steel support shell, an intermediate layer (1) of lead bronze, i.e. a copper alloy with a lead content of from 8 to 30%, a barrier layer (3) of electrochemically deposited iron or nickel and a bearing layer (4) cast or electrochemically applied to this barrier layer (3), the bearing layer (4) having a tin content of from 8 to 93%. The lead inclusions (2) at the surface of the intermediate layer (1) are removed by treatment with, eg, a solution of acetic acid and hydrogen peroxide whereafter the surface is ultrasonically cleaned before the barrier layer (3) is applied. <IMAGE> |
