Currently, it is known that infrasonic axial fluctuations affect various properties of metals. We conducted experimental studies to study the resistance of metals to corrosion in the field of infrasonic axial impacts. The subject of the study was the change in the properties of the surface of metals. It is established that when exposed to low frequency axial fluctuations in the range of 2-60 Hz occur changes in the processes of surface treatment of metals. Experimentally, optimal frequencies were found at which the effect of low frequency fluctuations becomes max. At the same time, each system under study has its own optimal experimentally detected frequency. Absorption spectroscopy is used to obtain results for the next systems: HCl – H2O2 – Cu; FeCl3 – Cu; KI – I2 – Cu; HCl – H2O2 – Al; KI – I2 – Fe.The use of the experimentally developed method of low frequency axial action allows increasing the speed of metal surface treatment up to 5 times. The study of the interaction of metals with electrolyte solutions in the field of low frequency fluctuations allows us to create new measures of protection against corrosion, as well as to develop new technological processes and solutions for surface treatment of metals and alloys for further implementation in the production process.
