摘要: 研究了铝离子与C_2O_4~(2-)复配对水中碳钢腐蚀的抑制作用。并用离子色谱技术研究了添加C_2O_4~(2-)后铝离子在水中的存在形态。发现铝离子与C_2O_4~(2-)络合,从而改变了在碳钢表面形成保护膜的条件和机构,导致了缓蚀作用的协同效应,进一步改善了铝离子的缓蚀性能。

Abstract：The inhibition effect of aluminium ion in combination with C_2O~(2-)_4 ion on corrosion of mild steel in water has been investigated. The state of Al~(3+)after adding C_2O_(2-)_4 ion has also been studied by Ion Chromatograph(IC)method. It was found that aluminium ion complexed with C_2O(2-)_4 ion,thus changed the condition and mechanism of film forming on the surface of mild steel,and thereby resulted in synergistic effect of the inhibitors. With a result,the inhibitive effect of aluminium ion considerably increased.
