铝在各种介质中腐蚀行为的研究

The Investigate of Corrosion Behavior about Aluminium in Defference Mediums

用线性极化、交流阻抗、塔菲尔斜率等电化学方法对铝在 3%NaCl和盐酸中及在上述溶液中加有少量胺类缓蚀剂的各种介质中的腐蚀行为进行了研究实验结果表明 ,在上述溶液中加有缓蚀剂均对铝有缓蚀作用 ,并对其缓蚀机理进行了初步的探讨 .

Line polarization,AC impedance,Tafel slope,electrochemistry methods have been applied to investigate the corrosion behavior of aluminium dipped in the 3% sodium chloride solution and hydrochloric acid both with minim amine inhibitors.The result shows that these inhibitors have positive effects on aluminium and its mechanism has been discussed primarily.
