The chaos theory was used to analyze electrochemical noise(EN) data for corrosion detection during coating degradation and stress corrosion cracking(SCC) process and insightful results were achieved by correlation dimensional characterization of localized corrosion. Analysis of electrochemical potential noise(EPN) during corrosion degradation of novolac epoxy coated on tinplate indicated that number of correlation dimensions corresponding to EPN tended to increase as localized corrosion accelerated. In addi...
