- Аннотация: The ergodicity of electrochemical noise of corrosion process with respect to the three-dimensionalChebyshev spectrum is studied. The electrochemical noise of “two identical electrodes of steel St-3 in theNaCl + benzotriazole solution” corrosion system is measured. The use of the Chebyshev noise spectra in thetest for the ergodicity of electrochemical noise is dictated by the fact that the intensity of the second andhigher Chebyshev spectral lines is resistant to the trend of electrochemical noise. It is found that in the initialperiod of interaction between the electrode and electrolyte, the electrochemical noise of the corrosion processis characterized by a weak ergodicity. However, even in 2.5 h, the ergodicity test shows that the steadystate is reached. A similar situation is observed for the electronic noise of measuring equipment. The test forthe ergodicity of electronic noise using the second component of three-dimensional Chebyshev spectrumshows that the steady state is reached in 30 min after switching on the measuring equipment. The ergodicitytest with respect to the second component of three-dimensional Chebyshev spectrum can be used for theanalysis of ergodic properties of random noise of any nature even under the conditions of strong trend.
