| 摘 要： | 用电化学方法比较研究了２－巯基苯并恶唑（ＭＢＯ），苯并三唑（ＢＴＡ）和２－巯基苯并噻唑（ＭＢＴ）在３％ＮａＣｌ，０．１ｍｏｌ／Ｌ ＨＣｌ和０．５ｍｏｌ／Ｌ ＨＣｌ溶液中对铜的缓蚀性能，在３％ＮａＣｌ溶液中，ＭＢＯ表现出稍优于ＢＴＡ，远高于ＭＢＴ的缓蚀能力；与ＢＴＡ和ＭＢＴ相比，在０．１ｍｏｌ／Ｌ ＨＣｌ和０．５ｍｏｌ／Ｌ ＨＣｌ中，ＭＢＯ对铜的腐蚀有突出的缓蚀效果。

| Abstract: | A comparison investigation of the inhibition of benzotriazole (BTA), 2 mercaptobenzothiazole (MBT) and 2 mercaptobenzoxazole (MBO) for copper corrosion in 3% NaCl, 0 1mol/L HCl and 0 5mol/L HCl solutions was carried out by means of potentiodynamic polarization In 3% NaCl solution, MBO possessed inhibition capacity close to that of BTA, but it was much better than MBT In hydrochloric acid solutions, the inhibition of MBO was the most prominent in the three inhibitors Furthermore, prolonged immersion of copper electrode improved the inhibition of MBO and BTA in acid media |
