Abstract

Purpose. We consider the system: cyclic-loaded steel - electrolyte. The kinetics of corrosion-mechanical development of cracks is controlled by potentiometric method. The signal in the process of degradation of steel, has three components: a slow decline in capacity, short pulses occurring at the time of the development of cracks and noise due to extraneous factors. At the first stage of the analysis signal is removed by filtering the low frequency trend. Next, set the parameters of statistical methods of noise and information stands pulse frequency signal. The sequence of the pulses and the intensity of their occurrence allows to evaluate the current state of the object and predict the residual life.
