Hybrid syntactic foams with AlSi12 aluminum alloymatrix were produced bylow pressure infiltration and the wear properties were investigated by pin-on-disc method against a low carbon steel disc counterpart. As reinforcement iron(GM;~Ø1.9mm)and two ceramic type(GC;~Ø1.4mmandSLG; ~Ø0.12mm)hollow spheres were used. The volume ratio of GM-GC hollow spheres variedand also SLGþGC hybrid composites were produced. The tests inlubricated condition showed significantly different roperties to the dry tests,due to the different oil reservoir capacity of the open hollow spheres in the contact zone, depending on the reinforcement type and ratio. The coefficient of friction, specific wear, height loss and surface damage of the specimens were strongly dependent on the reinforcement type.
