摘要：
An investigation of the electrochemical noise generation was conducted in Mattson's solution (ammoniacal copper sulfate solution) of pH 7. 2 under free corrosion potential. All of the spectra appeared as a low frequency plateau with a roll-off at high frequencies. In addition, plastic replicas were examined by scanning electron microscopy (SEM) to follow the progress of crack initiation and growth.
