用腐蚀失重法和电化学阻抗谱研究了泡沫SiC/Cu双连续相复合材料和对应的基体材料纯Cu在3.5%NaCl水溶液中的腐蚀行为。结果表明,在3.5%NaCl水溶液中,泡沫SiC/Cu双连续相复合材料比纯基体Cu具有更大的腐蚀敏感性,主要原因是该复合材料的特殊结构及残余应力的存在致使泡沫筋微孔中的Cu严重腐蚀。 The corrosion behavior of foamed SiC / Cu bicontinuous phase composites and the corresponding matrix pure Cu in 3.5% NaCl aqueous solution were studied by corrosion weight loss method and electrochemical impedance spectroscopy. The results show that in 3.5% NaCl aqueous solution, the foam SiC / Cu bicontinuous phase composites have greater corrosion sensitivity than the pure Cu, which is mainly due to the special structure and residual stress of the composites, Cu in the serious corrosion.
