Title: INVESTIGATION OF THE WEAR RESISTANCE OF TRIBOLOGICAL SYSTEMS COMPOSED OF ALUMINIUM-SILICON ALLOYS: PART 2 Keywords: hypereutectic aluminium-silicon alloy, mass loss, tribosystems, wear rate, wear resistanceAbstract: The present work represents the wear of contact systems (tribosystems) in boundary lubrication mode during reversible reciprocating motion. The investigated tribosystems are composed of non-standardized hypereutectic aluminium-silicon alloys. The samples, involved in the friction pairs, are from the alloys AlSi2 1Cu3 CrMn, AlSi25 Cu4 Cr and AlSi25 Cu5 Cr, and the counterbodies have the compositions AlSi21 Cu5 MgCr and AlSi21 Cu5 Cr. The investigated alloys were modified with P and subjected to T6 heat treatment. Artificial aging was carried out under different parameters (temperature and holding time). Results were obtained for mass wear, wear rate and wear resistance of each sample, counterbody and overall for the tribosystem.
