MULTILAYER COMPOSITIONAL MATERIAL FOR PLAIN BEARINGS, MANUFACTURING AND APPLICATION Russian patent published in 2009 - IPC F16C33/12 B32B15/01 C23C30/00 

FIELD: machine building.

SUBSTANCE: invention relates to multilayer compositional materials for plain bearings or bushes which are desirable to use sliding layers not containing lead. Multilayer compositional material contains base layer, layer (3) of bearing metal from copper or aluminium alloy, nickel intermediate layer (2) with thickness exceeding 4 mcm, and sliding layer (1) which contains from 0 to 20 wt %, of copper and/or silver, the remaining part - bismuth. Sliding layer is obtained by method of galvanic precipitation from methyl sulphoacid electrolytes.

EFFECT: reduction of production-technological expenditures in manufacturing multilayer compositional material, more homogeneous distribution of materials in matrix and, as a result, in case of vibrations - smaller probability of low-melting eutectic regions emergence, increase of operational reliability.
