METHOD OF PRODUCTION OF COPPER-BASED ANTI-FRICTION MATERIALS Russian patent published in 2003 - IPC

FIELD: powder metallurgy; methods of production of copper-based anti-friction materials for manufacture of tribotechnical parts (self-lubricating wear-resistant sliding bearings in friction units). SUBSTANCE: proposed method includes preparation of powder mixture by mechano-chemical alloying at addition of solid lubricant and getter, cold molding, sintering and hot extrusion; after hot extrusion, material is subjected to hardening at temperature of 850±30^°C, cooling in bath filled with water and aging at temperature of 400±50^°C followed by cooling together with furnace. EFFECT: increased percentage of solid lubricants; enhanced strength characteristics. 1 tbl
