Abstract:
The principle on the pitting electrochemical noise detected by using wavelet transform was described briefly and the signal of pitting electrochemical noise was analyzed for commercial pure aluminum in 3.5 % NaCl solution. The result showed that wavelet transform could not only obtain the waveform characteristic of pitting signaland system noise in the multi-scale space, but also detect the waveform of pitting electrochemical noise according to the transmitting characteristic of the maximum module of wavelet coefficients, which represented the waveform characteristic.
