Mechanical and tribological properties of aluminium-base composites produced by the recycling of chips

In this paper the results of investigations of the manufacturing and proper ties of bearing materials produced by the recycling of aluminium and alumin ium-bronze chips are presented. Bearing composites were produced by the col d compaction and hot extrusion (at 520 degreesC) of comminuted and mixed al uminium and aluminium-bronze chips. The wear and the coefficient of frictio n of the composites produced were determined as a function of the percentag e of the reinforcing phase (aluminium-bronze granulated chips) and the load applied by means of a pin-on-disc wear testing machine.
