Abstract: A component is immersed into an electrolyte with a specific speed and an initial polarizing current intensity is applied, which is high enough to generate on the surface of the treated component, which is immersed in the electrolyte, moving microplasma discharges. The component is held until the formation of a coating of a specific thickness. The lowering phase of the voltage, at which a coating forms, is carried out by lowering the voltage to a value which corresponds with the beginning of the extinction of the microplasma discharges and then maintaining it until the complete extinction of the isolated wandering microplasma discharges. Then the component is taken out of the electrolyte and is cooled.

Abstract: A method for microplasma electrolytic processing a surface of an electroconductive material, involves establishing an electrical circuit between this material, as a first electrode, and a counterelectrode, as a second electrode, by immersing the first electrode into an electrolyte that is in contact with the second electrode and applying an electrical voltage across the first and second electrodes with a power source. In a first step, only a portion of the surface of the material is immersed in the electrolyte, the size of that portion being dependent on an output power of the power source, a composition of the material, an electric regime used, a composition of the electrolyte, and a minimal current density at which a process of microplasma oxidation is stable. The surface of the material is then completely immersed in the electrolyte while the voltage is regulated to cause a current value I(t) between the first and second electrodes ranging from 0.9I<I(t)1.
