Operating properties of composite antifriction materials on the base of aluminium alloys wastes for printing equipment
Abstract: The questions of using materials for friction units, first of all, the antifriction materials in particular on the aluminium alloy-based metal matrix take a central place in general problem of increasing the polygraph knife-machines quality. Endurance of such equipment determines a level of printing output quality. This paper summarizes the recent developments of aluminium alloy AK12MMgN industrial grinding wastes-based usage for new antifriction materials and knowledge about their manufacturing technology; specific examples will be given. Research results of new composite material physical, mechanical and tribological properties in comparison with cast alloy have been presented. The principle possibility to use the valuable industrial grinding wastes of ferrous and color metals for manufacturing of an effective parts of polygraph machines was shown.
