Dvoynenko O. The micro-and nanoscale surface structuring by magnetoelectrolysis and magnetically controlled corrosion methods

Object: processes of electrochemical deposition and etching in aqueous electrolyte solutions under the influence of an external constant magnetic field and domain structure of ferromagnetic cylinders. The purpose: determination of the influence of the domain structure of a ferromagnetic sample with cylindrical shape on a quasiperiodic structure etched in a solution of electrolyte and structural characteristics of electrodeposition of Ni. Methods: optical microscopy (МИКМЕД-5), scanning electron microscopy (РЕМТ-103), X-ray diffractometry (ДРОН-3), hysteresisography (УИ.ФИ - 400/5). Results: A new method for high-gradient ferromagnetic nozzle production with controlled surface structures using magnetically controlled Ni plating on ferromagnetic cylindrical samples and grids for industrial and biomedical applications is found out. For the first time the correlation between the quasi-periodic distribution of magnetostatic field on the surface of steel cylinders of different diameter to the size of quasiperiodic etching figures by an external magnetic field is determined. For the first time the correlation between the quasi-periodic spatial distributions of the magnetostatic fields on the surface of steel cylinders of different diameter with the size of quasi-periodic etching figures under the influence of an external magnetic field is revealed. Field of application: solid state physics, magnetism, nanophysics
