FIELD: process engineering.
SUBSTANCE: invention relates powder metallurgy, particularly, to plain bearings with steel base and sintered bronze material. Bearing comprises sintered compacted powder material of insert from copper-tin-bismuth allow and powder of the mix of metal compounds bonded with metal base of bearing insert. Said alloy includes copper-tin matrix with bismuth islands dispersed therein. Said mix of metal compounds features mean grain size smaller than 10 mcm and may include powder of Fe3P and MoSi2.
EFFECT: high wear resistance, durability and surface lubricity.
