Production and Tribological Characterization of Advanced Open-Cell AlSi10Mg-Al2O3 Composites

In this study, advanced open-cell porous AlSi10Mg-Al2O3 composites have been successfully fabricated by replication of NaCl space holders. The tribological behavior under dry sliding conditions at room temperature with different pore sizes was studied via the pin-on-disk method, and wear parameters, such as coefficient friction (COF) mass wear, were determined. Micro-hardness tests performed to investigate change in mechanical properties after processing composite materials. Microstructural observation conducted means light microscopy scanning electron (SEM) along chemical micro-analysis using an X-ray energy-dispersive spectroscopy (EDS) system. obtained results revealed that investigated possess lower COF than AlSi10Mg material when subjected same test conditions. Furthermore, it also reported effect size is insignificant COF, relation larger pores shows better results.
