A study of the surface structure of electrodes during discharge in an electrolyte in a magnetic field

The occurrence of microstructures on the surface of tungsten and titanium electrodes during discharge in an electrolyte in the presence of a magnetic field has been studied. Electrical characteristics of the discharge at various modes were obtained. The plasma temperature in the near-electrode region was measured using spectral methods. Conical and pointed formations with sizes up to $10$ $\mu$m occurred on tungsten electrodes. The appearance of microspheres and porous surfaces was observed on titanium electrodes. The growth of these surface structures accelerated and their characteristics improved under the effect of a magnetic field. The mechanism of growth of the observed microstructures are discussed.
