CHARGE FOR ANTIFRICTION COMPOSITE MATERIAL ON BASIS OF ALUMINIUM AND SINTERED ANTIFRICTION COMPOSITE MATERIAL ON BASIS OF ALUMINIUM, RECEIVED WITH ITS APPLICATION Russian patent published in 2009 - IPC C22C1/04 C22C21/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to powder metallurgy, particularly to sintered composite material on the basis of aluminium for details of triboengineering purpose - bushes, friction bearing, compaction, step-bearings. Charge for composite material on the basis of aluminium, containing, wt %: transition metal powders, selected from Fe, Cr, Ni, Ti, Co, V, Zr, - 7.5-20, alloying elements, selected from Cu, Zn, Si, Mg, Li, Sn, Pb - 0.3-12; aluminium - the rest. Sintered composite material on the basis of aluminium, received with application of mentioned charge includes alloyed aluminium matrix and reinforcer in the form of aluminide particles of composition Al₃X, where X - Fe, Cr, Ni, Ti, Co, V, Zr, at following ratio, wt %: reinforcer 30-60, matrix - the rest.

EFFECT: received material allows high hardness and triboengineering characteristics.
