Abstract
The SCC processes of the high strength carbon steel alloy was investigated by the electrochemical noise generation during corrosion processable. The investigation was carried out under free corrosion potential in an acidified NoCl solution (3.5% NoCl + dil. H 2so•>. poisoned with Na 2S (500ppm). The electrochemical noise was observed as spontaneous fluctuations of potential. The readings obtained were anal used using the maximum entropy method. The spectrum standard deviation and the roll-off slop~ ore the Measured parameter s which appeared to give the clearest indication of the results. All the noise amplitudes generally increase with decreasing frequency a•d the power spectral density are inversely proportional to some power of the. frequency thus indicating '1/f' or 'flicker• noise.
