Advanced antifriction composites based on tool steel grinding waste for printing machines’ friction units

Abstract

Antifriction parts in the printing machines’ friction units operate at high rotation speeds 1000 rpm and more, at loads of 1.5−7.0 MPa in air, which causes the working surfaces heating up to 400−500°C. A wide range of cast and powder antifriction materials based on iron, copper, etc. have been developed and are currently used for severe working conditions [1−3]. In modern friction units, cast materials have unsatisfactory performance properties (high coefficient of friction and wear).
