摘要：
SiC foam ceramic reinforced aluminum matrix composites (SFCAMCs) were prepared by squeeze casting aluminum alloy (Al–23Si) into the SiC foam ceramic with different pore sizes, and the corrosion behavior of the SFCAMCs was studied in NaCl solutions. Static immersion corrosion tests were conducted at 20 °C, 50 °C and 80 °C, respectively. Corrosion morphology and products were analyzed by scanning electron microscope, energy dispersive system and X-ray diffraction. It was found that the corrosion rate of SFCAMCs increases as the temperature rising, and the bigger pore size of SiC foam ceramic reinforcement, the better corrosion resistance of SFCAMCs.
