Electrochemical Noise Chaotic Analysis of NiCoAg Alloy in Hank Solution

Electrochemical Noise Chaotic Analysis of NiCoAg Alloy in Hank Solution

The potential and current oscillations during corrosion of NiCoAg alloy in Hank solution were studied. Detailed nonlinear fractal analyses were used to characterize complex time series clearly showing that the irregularity in these time series corresponds to deterministic chaos rather than to random...
