%X SiC/Al co-continuous composites were fabricated by the squeeze casting method, the surface of SiC foam was treated by an aqueous solution of NaOH and an aqueous solution of K2ZrF6, and the effects of treatment on the performance of SiC/Al co-continuous composites were investigated. The results show SiC foam got the optimum coarse when they had been treated by an aqueous solution of NaOH for 12 min. The treatment changed the appearance of struts of foam perform and improved the bonding of interface, the continuity of composites, so the mechanical properties of composites were increased. The composites that were treated by K2ZrF6 have the best bonding of interface and the highest strength that is 5 times of pure aluminum matrixes.
