Monitoring of corrosion of metals and alloys is a time consuming work even though various techniques are now available. The random-pulse method developed by Ichise et al. for electrochemical analysis has been applied to the examination of corrosion behavior and its rate. The current response was obtained as a function of potential, and was transformed to the spectral data to compress the informed data from the system by fast Walsh transformation. The behavior and the rate of corrosion were well elucidated by using the transformed data. The average current density, or the corrosion rate, agreed with the result of the polarization measurement. Therefore, it is concluded that the random-pulse method combined with a pattern recognition technique is applicable to investigate the corrosion of metals and alloys within one minute.
