【摘要】将氧化铝纤维增强铝基复合丝(AF/Al)的原始试样和经过热暴露、热循环处理的试样分别在3.5%NaCl水溶液、0.05mol/L稀盐酸、1%Na2CO3水溶液中进行腐蚀试验,观察试样的腐蚀现象,并进行显微分析,探讨氧化铝纤维增强铝基复合丝在盐碱酸三种溶液中的腐蚀机理,研究了热处理对其腐蚀行为的影响。结果表明,该复合丝在三种溶液中均有腐蚀发生,在盐、碱溶液中腐蚀较轻;热处理对复合丝腐蚀行为影响不明显。更多还原

【Abstract】 The corrosion behavior and mechanism of Al₂O₃ fiber reinforced aluminium composite wires（AF/Al wires） were studied by corrosion tests and microscopy in three kinds of solution（3.5%NaCl,0.05mol/L diluted HCl and 1%Na₂CO₃ respectively） and in three states（primary state,hot exposure and thermal cycle respectively）.The influence of heat treatment on the corrosion behavior of AF/Al wires was also discussed.更多还原
