Effect of manufacture technology on properties of aluminium alloy wastes-based bearing composites for printing machines

Abstract

The paper studies the effect of the technological parameters for the production of new aluminium alloy wastes-based antifriction composite materials on the structurization and tribotechnical properties at friction (bearings perform at a sliding speed of 1.0 m/sec and a pressure up to 5.0 MPa in air). The study focuses on the features of structure formation in the composite with Al–alloy AK12MMgN wastes matrix, their role in friction behavior of new composite material under severe operating conditions. It was shown the principle possibility of successful use of the valuable industrial colour metals grinding wastes for manufacturing of effective friction parts for printing machines.
