Popis: In this present work, we have studied the effects of the amount and size of reinforced zircon sand particles (ZrSiO4) on the cell geometry and wear performance of aluminium alloy (LM13) composite foam. An Al–Si alloy (LM13) as a matrix, zircon sand particles of different sizes as reinforcement, and CaCO3 as a blowing agent were used to develop the alloy foam and hybrid composite foam. A stir casting process was used to develop alloy foam and its hybrid composite foams. The tribological study of LM13 alloy foam and its composite foam was carried out by using a pin on disc machine under dry sliding conditions at different loads in the range of 9.8–49 N. The results show that a higher amount of zircon sand particles above 5 wt.% with decreasing size leads to a decrement in the size of the cell having thicker cell walls. A comparative tribological study of alloy and its composite foam based on density, cell size, ligament and node size, and foam stability has been presented. An increment in the wear resistance was observed with increasing the amount and also with decreasing the size of reinforced particles.
