Royik T. A., Dorfman I. E. Formation properties of new wear-resistant details for polygraphic equipment based on alluminum-alloys wastes
    The paper is concerned influence of technological conditions for obtaining the formation of complex structures and properties of antifriction composite materials based on aluminum-alloys wastes АК12ММгН. Structural studies have been conducted. It is shown that in the tested material available reinforcing phases (intermetallics) have high density and uniform distribution on the sample section. Mechanical, physical and tribotechnical properties of composite materials based on aluminum-alloys wastes АК12ММгН are examined and compared with cast analogue. It should be noted that tribotechnical properties of powder alloy is higher than cast analogue. The mechanical properties of composite materials are not inferior cast alloy. This behavior of the new material is explained by significant differences of structure formation of the powder alloy and cast alloy arising from the various principles of synthesis of materials. This is caused by different principles of synthesis of materials.
