METHOD FOR PRODUCTION OF ANTIFRICTION MATERIALS Russian patent published in 1997 - IPC

Abstract RU 2093308 C1

FIELD: powder metallurgy; in particular, methods for production of antifriction sintered materials used in manufacture of self-lubricating bearings and seal rings. SUBSTANCE: method includes mixing of powdery components with introduction into mixture of plasticizers, molding, sintering, impregnation with lubricant or with some other antifriction substances. In this case, powder components for mixing are taken with particles of solid lubricant sizing 30-90 mcm, and those of powders of material bases sizing 5-20 mcm. Mixing is carried out in parallel successive manner: first solid lubricants are mixed with plasticizer, simultaneously mixed are powder components of material bases, and then obtained mixtures are mixed. EFFECT: higher efficiency. 1 tbl
