TO INVESTIGATION OF SUITABLE CELL FOR CORROSION MONITORING OF 6061 ALLOY

One major application of electrochemical noise (EN) analysis for corrosion studies is the estimation of corrosion rate via impedance measurement. The measurement involves coupling two electrodes, whereupon the associated EN is measured and the noise resistance and the spectral noise impedance are computed. However, the two electrodes are required to be ‘‘nominally identical’’ (i.e. symmetrical) for the noise resistance and spectral impedance techniques to be valid. This paper proposes that application of asymmetry electrodes with different size to improve the pitting corrosion monitoring of 6061 aluminum alloy
