Abstract 7075 Al/SiC composites foam was manufactured by spark plasma sintering (SPS)-dissolution method with SiC volume fractions of 10vol% and NaCl volume fraction of 40%. The ball milling time, sintering property, pore structure, and tribological properties were systematically studied. The results show that 7075 Al/SiC composites foam with the average pore size 250 μm and uniform distribution of SiC can be obtained under 10 min sintering at 550 ℃ and 2 hours of ball milling. The form’s microhardness, with 10vol% SiC, increases to 132HV0.2. The friction coefficient of 7075 Al/SiC composites foam is 0.31—0.34 by Pin-on-Disk test. After wearing against GCr15 ball, the specific wear rate of the 7075 Al/10vol% SiC composite foam is 3.373×10-4 mm3/(N·m), while the specific wear rate of the 7075 Al foam is 0.993 4×10-3 mm3/(N·m). After wearing against Al2O3 ball, the specific wear rate of the 7075 Al/10vol% SiC composite foam is 3.986×10-4 mm3/(N·m), whereas the specific wear rate of the 7075 Al foam is 2.12×10-3 mm3/(N·m). The addition of SiC particles significantly improves the wear resistance, with the wear mechanisms mainly attributed to adhesive wear and abrasive wear.
