FIELD: machine building.
SUBSTANCE: method for manufacturing anti-friction layer of sleeve half-bearing consists in oversized boring after sleeve casting and its plastic deformation. Plastic deformation is made within the range of recrystallisation temperature of matrix alloy phase, but not exceeding the temperature of melting of disperse phases at average speed of deformation 10-2≤ε≤10 s-1. Deformation is made in several transitions with changing of direction by transitions to opposite one. Deformation is done by tool, the material, thermal processing and roughness of which corresponds to the material of shaft neck joined with the bearing.
EFFECT: increase of product wear-resistance due to creation of small grain structure of top layer, provision of positive gradient of mechanical properties by depth, reduction of surface roughness due to smoothing microroughnesses by breaking-in roller and reduction of material wearing-in period.
