“…Results of multicomponent saturation in a solution that contains ammonium chloride, carbamide, boric acid, and sodium thiosulfate showed that the content of boron in the outer layer was 4 % [10]. Saturation at 800 °C for 5 min with subsequent quenching in an electrolyte leads to the formation of a modified layer with a thickness of up to 35 μm and a surface microhardness of up to 600 HV.…”

The paper shows the possibility of plasma electrolytic polishing of the steel surface after its chemical-thermal treatment. Positive results of the plasma electrolytic polishing are obtained for low carbon steel after its anodic plasma electrolytic boronitriding. An X-ray diffractometer and a scanning electron microscopy were used to characterize the phase composition of the modified layer and its surface morphology. Surface roughness was studied with the use of a roughness tester. The hardness of the treated and untreated samples was measured using a microhardness tester. Corrosion properties of the samples treated surfaces were evaluated using potentiodynamic polarisation tests in solution of sodium chloride. The reduction of the surface roughness of 1.7 times and the corrosion current density of 1.5 times of boronitrided steel by plasma polishing using mode of current interruption for 2 min without changing the structure of the diffusion layers is shows.
