无须对电化学阻抗谱的数据进行精确分析，只要对高分子涂层涂覆钢的阻抗的某些特征值进行分析，就可以快速评估涂层的性能，结果表明，特征频率ｆｂ、最大相位角处的频率ｆθｍａｘ、相位角最小值Φｍｉｎ及其所对应的频率ｆｍｉｎ都能方便、快速地评估涂层的防护性能。
An analysis of sane characteristic values of the impedance of polymer-mted steel was perfod to assess mting performance in a short time without rigomus analysis of data fxun EIS. Results of the analysis suggested that the break-point frequency (fb) , the frequency (fo-) of the phase-angle maximum, the phase- angle minimum observed at h~ghfrequencies (@-) and the frequency (f-) could be used for this purpcse.
