“…The increasing interest in this type of materials is dictated by the satisfactory strength-to-density ratio, combined with high tribological properties compared to the alloy matrix without reinforcement. The performance properties of composite products (pistons, bushings, bearings, disks), especially the resistance to wear under friction, depend mainly on the type, size, shape and content of the reinforcing particles [5][6][7][8][9].…”

The aim of the study was to describe the structure of composites based on the AlSi7Mg2Sr0.03 alloy matrix reinforced with SiC particles added in an amount of 10% and with a mixture of SiC and GR particles added in a total amount of 20%. Studies of the composite structure, were carried out by scanning electron microscopy (SEM). Based on the results of chemical analysis in microregions, an increased content of elements such as Mg, O and Si and of the precipitates was observed at the interface. In many places in the examined sample, GR particles formed partly disintegrated conglomerates with well developed boundaries. The effect of the content of particles of the reinforcing phase on the functional properties of the composite was investigated during studies of abrasion. The lowest mass loss of 5,33mg was obtained for the AlSi7Mg2Sr0.03 alloy reinforced with 10% SiC particles.
