FIELD: metallurgy.
SUBSTANCE: invention relates to powder metallurgy, particularly to a method of producing a bimetallic strip with an antifriction coating based on copper from metal powders for making sliding bearings. Starting charge contains, wt%: 9–11 iron powder with particle size ≤40 mcm, 9–11 lead powder – ≤40 mcm, 0.5–1.0 aluminum oxide powder (Al2O3) – ≤0.1 mcm, the rest is copper – ≤70 mcm, preliminary subjected to rolling at pressure of 200–250 MPa and placed on steel base. Obtained composition is rolled with steel-based reduction 70–80 % and subjected to heating to temperature 800–850 °C in hydrogen atmosphere with isothermal holding for 15–30 minutes. Cooling is carried out in the same atmosphere.
EFFECT: higher strength properties, wear resistance and resistance to contact destruction.
