摘要
Harmonic current was measured for a type 316 stainless steel to investigate the effects of frequency on the harmonic current in NaCl solutions with pH 1.6 and 1.9. Harmonic current increases, and polarization resistance decreases with increasing frequency in both solutions in charge transfer condition. The increase in harmonic current with frequency was also observed in mixed control condition of charge transfer and diffusion. The square of harmonic current is linearly dependent on that of frequency in charge transfer condition, but not in mixed control condition. To fit the experimental data in the latter condition, a simple relation was developed by a dimensional analysis. According to the equation developed, the square of harmonic current is linearly dependent upon the frequency in mixed control condition.
