FIELD: manufacturing technology.
SUBSTANCE: invention relates to friction materials intended for operation in friction assemblies of machines and mechanisms under liquid friction conditions. Copper based material containing 4–7 wt% of tin and 9–12 wt% of graphite is produced using 35–40 wt% of iron powder.
EFFECT: higher friction coefficient, increased stability of moment of friction forces, reduced pressure of coining, obtaining hardness 15–23 HB, porosity 17–24 %, as well as increased pressure on material at operation up to 5 MPa and sliding speed up to 11 m/s.
