Контроль коррозии стали методом высших гармоник намагниченности

Abstract

In this paperwe study the correlation Fourier spectrum of the hysteresis loops of steel its corrosion resistance. The structural changes occurring in steel as a result of its processing (thermal and mechanical) affect the corrosion resistance. The structural changes in the steel during its thermal processing may include, for example: stress relief, precipitation of carbides and their changing. The aforementioned changes in steel greatly affects the shape of the loop, out as a harmonic Fourier spectrum is sensitive to the waveform change, the method of Fourier analysis may provide an additional means of nondestructive inspection of corrosion resistance of steels.
