METHODS FOR EVALUATING THE PERFORMANCE OF PROTECTIVE COATINGS WITH EIS
用EIS快速评估有机涂层防护性能的方法

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.
