| 摘 要： | 采用失重，腐蚀电位测试，交流阻抗等方法研究了氨基硫脲对锌在２６％氯化铵介质中的缓蚀作用机理，研究结果表明，ＴＳＣ对锌在氯化铵中的腐蚀有较好的抑制作用，其作用机制为几何覆盖效应。ＴＳＣ在锌表面的吸附近似符合Ｌａｎｇｍｕｉｒ等温式。

| Abstract: | The corrosion behavior of zinc in ammonium chloride solution with thiosemicarbazido(TSC) wasstudied by means of corrosion potential measurement, electrochemical impedence spectroscopy and weight-loss method. The experimental results showed that TSC had remarkable inhibition effect on the corrosionof zinc in 26% ammonium chloride solution. The inhibition efficiency of the TSC increased with theincrease in its concentration up to 0.2g.L-1 . The inhibition of TSC for zinc was found to be the geometricblocking effect, and its adsorption isotherm approximately followed Langmuir isotherm equation. |
