COMPOSITE ANTIFRICTION MATERIAL AND ITS MANUFACTURING METHOD Russian patent published in 2017 - IPC C08J5/16 C08L27/18 B22F3/00

Abstract RU 2614327 C2

FIELD: metallurgy.

SUBSTANCE: invention refers to antifriction materials. Composite antifriction material based on bronze-filled PTFE consists of tin and lead bronze, PTFE and ultradisperse diamonds at the following component ratio, wt %: PTFE 5-6; ultradisperse diamonds 0.065-0.187; the rest is tin and lead bronze. Method of material manufacturing involves preliminary mixing of PTFE and ultradisperse diamond powders. Then the mix is mixed with tin and lead bronze powder. Obtained three-component mix undergoes cold pressing at 8000-9000 kgf/cm² followed by hot pressing at 355-400 °C and pressure of 4500-5500 kgf/cm². Hot-pressed workpiece is cooled down to room temperature under the pressure of hot pressing.

EFFECT: enhanced mechanical strength and tribo-technical parameters of composite antifriction material.
