Abstract

In the process of electrochemical dynamics system,the phenomenon of the random fluctuations of electrochemical parameters(electrode potential,cell current,etc.)is called “Electrochemical Noise”(ECN).Wavelets analysis is one new data analysis technique which has undergone a breakthrough in the area of mathematics and singnal processing in recent years.In this paper,the technique of continuous wavelet transform has been employed to investigate electrochemical noise data,and the chaotic nature of corrosion process has been manifested.
