Mechanisms of Destruction by Alternate Current

“…In the range II the metal destruction rate is more than rate of electrochemical corrosion destruction process. According to [3], the alternate current in this range intensifies the electrochemical process of natural corrosion in 3-5 times. The electrochemical and physical phenomena occurring here is still a subject of study.…”

“…Russian and foreign scientists had discovered that steel constructions having waterproofing coat, such as oil-and gas-main pipelines, were liable to destruct under the action of alternate current, caused by electromagnetic influence of objects of electroenergetics [2,3]. The advanced theories of the destruction are diverse and do not give generalized understanding of physical base of the process.…”

“…The advanced theories of the destruction are diverse and do not give generalized understanding of physical base of the process. While in [2] had claimed that if potentials of pipeline exceeded 4-10 V the corrosion occured in isolation defects during positive half-wave of alternate current, the [3] had concluded that under the action of alternate current the corrosion practically was absent.…”
