Title: INVESTIGATION OF THE WEAR RESISTANCE OF TRIBOLOGICAL SYSTEMS COMPOSED OF ALUMINIUM-SILICON ALLOYS: PART 1
Keywords: eutectic and hypereutectic aluminium-silicon alloy, tribosystems, wear resistance

Abstract: The present work represents the wear of contact systems (tribosystems) composed of non-standardized aluminium-silicon alloys in the boundary lubrication mode during reversible reciprocating motion. The studied samples are made of alloys with hypereutectic composition (AlSi21Cu3CrMn, AlSi25Cu4Cr, AlSi25Cu5Cr), and the counterbodies are complex alloyed eutectic alloys (AlSi12Cu5MgCr, Al-Si12Cu5Mn). The hypereutectic alloys are modified by P, the AlSi12Cu5MgCr alloy is complex modified by Be, Ti, B and P, and the AlSi12Cu5Mn alloy with Ti, B and Sr. The alloys were subjected to T6 heat treatment at different time-temperature regimes of artificial aging. Results were obtained for mass wear, wear rate and wear resistance of each specimen, counterbody and overall for the tribosystem.
