摘要
采用失重法、极化曲线法、电化学噪声以及电感法分别测定了Q235钢在模拟土壤中的腐蚀行为,并比较了各种方法的优缺点。结果表明,电化学噪声法测得的腐蚀速率与失重法接近,具有原位无损检测、数据真实可靠的特点,可以进行土壤腐蚀机理分析与腐蚀特性研究,该方法在土壤腐蚀研究方面具有较大优势。
The corrosion behaviors of Q235 steel in simulated soil were studied by means of weight loss method, polarization curve method, electrochemical noise, and inductance method. The advantages and disadvantages of the various methods were compared. The results show that the corrosion rate measured by the method of electrochemical noise was close to that obtained by weight loss method. The electrochemical noise method is good for in situ nondestructive testing, the data is credible. This method has greater advantages in studying soil corrosion and thus can be used in analyzing the corrosion mechanism and the corrosion characteristics.
