【摘要】 通过极化曲线及扫描电镜 (SEM)研究了巴比妥钠对硬铝合金 (LY1 2CZ)在 3 .5 %NaCl中的缓蚀作用机制 .结果表明 ,巴比妥钠对铝合金具有较好的缓蚀作用 ,并且能提高铝合金在NaCl溶液中抗点蚀的能力 ,这种作用主要是通过在铝合金的表面形成不溶性盐转化膜来实现的更多还原

【Abstract】 The inhibitive mechanism of sodium barbital for aluminium alloy in 3.5% NaCl solution was investigated by potentiodynamic polarization and SEM. With the addition of sodium barbial, the inhibitive efficiency increases. The inhibition of sodium barbital results from forming a thin conversion film on the surface of aluminum alloy, which increase the resistance of corrosion.更多还原
