摘要: 本文介绍了采用通用微型计算机建立的府蚀电化学在线测量系统。它由微计算机控制的恒电位仪、一系列电化学测试控制软件和腐蚀参数测定的应用程序组成。通过计算机程序安排,该系统能自动完成阶梯波电位讯号的产生、电化学测试的进行、数据的采集以及分析计算。由极化数据分析计算金属的腐蚀速度是通过解析腐蚀体系的动力学方程式得到的。通过迭代,解残差方程组,求出金属的腐蚀速度和塔菲尔常数。文章列举了本方法应用的实例,分析和讨论了方法的可靠性和适用范围。

Abstract：An on-line measurement system of corrosion electrochemistry with a usual microcomputer was established. It consists of a computer controlled potentiostat. a series of softwares for electrochemical measurement and applied programs for the determinations of corrosion parameters. By the arrangement of computer program, generation of a successive step signal, electrochemical measurement, and the acquisition, analysis and calculation of data have been performed automatically. Calculation of metal corrosion rates from polarisation data were taken with the aid of the kinetic equation of corrosion system. By solving the residual equations through iteration, the corrosion rates and Tafel constants can be obtained. Examples of this method are shown and experimental technique is introduced. The reliability and the field of application are also analysed and discussed.
