ANTIFRICTIONAL COMPOSITE POWDERED MATERIAL Russian patent published in 2008 - IPC C22C9/00 C22C1/05 B82B3/00 

FIELD: metallurgy.

SUBSTANCE: invention refers to powdered metallurgy, particularly to antifrictional composite powdered material, and can be used, for example, in metal working industry and paper processing industry at fabricating of wear resistant antifrictional materials. The composite material contains a copper powder of 100-160 mcm size at amount of 63.8-64.3 mass.%, granules of copper-plated graphite of 160-200 mcm size; at amount of 16-17% with copper contents in copper-plated graphite granules of 70-75 mass.%, granules of copper-plated polymer of 50-200 mcm size at amount of 7-9 mass.% with copper content in granules of copper-plated polymer granules 50-60 mass.%, granules of copper-plated nickel of 100-200 mcm size at amount of 3-5 mass.% with copper contents in granules of copper-plated nickel 25-35 mass.%, granules of copper-plated chromium of 25-75 mcm size at amount of 6-8 mass.% with copper content in granules of copper-plated chromium granules 30-40 mass.% and carbon nano pipes at amount of 0.2-0.7 mass.%. Such composition facilitates increased service life of friction units, upgraded hardness of a powdered matrix and increased wear resistance of composite material.

EFFECT: producing antifrictional composite powdered material facilitating increased service life of friction units, increased hardness of powdered matrix and increased wear resistance of composite material.
