BEARING ALLOYS BASED ON ALUMINUM AND ITS MANUFACTURING METHOD Russian patent published in 2016 - IPC C22C21/00 C22C1/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to compounds bearing alloys based on aluminum, as well as to methods for altering their metallographic structure of a combination heat treatment and plastic deformation, and can be used, for example, in the manufacture of plain bearings. Anti-friction alloy contains, by weight%: 8.0-12.0 tin; Lead 2.0-4.0; Copper 2.0-5.0; Silicon 0.1-1.0; Zinc 1.5-4.0; Titanium 0.02-0.2; Aluminium - the rest. A method for producing anti-friction alloy smelting includes anti-friction alloy of the composition for which the process of melting is heated to melt the aluminum alloying components to a temperature of 750-850°C carried out degassing and modification, and then poured the molten metal at a temperature of 740-760°C in preheated form.

EFFECT: technical result is an increase in strength, hardness and wear resistance of bearing metal while maintaining a high level of wear resistance due to reduction of internal stresses and creation of fine-grained structure with uniform soft structural component and small inclusions of solid phase based on copper and silicon.
