IRON-BRONZE POWDER COMPOSITE ANTIFRICTION MATERIAL

摘要

FIELD: metallurgy.;SUBSTANCE: invention relates to powder metallurgy, particularly, to high-strength composite antifriction materials for operation in high-load friction assemblies. Powder composite antifriction iron-bronze material contains, wt%: copper 8–30, tin 3–10 with respect to copper, nickel 2–16 with respect to copper, iron – the rest.;EFFECT: providing high hardness and strength, low coefficient of friction, resistance to impact loads, as well as operation in conditions of dry friction and lubrication at temperatures of up to 600 °C.;1 cl, 2 tbl
