Plasma Electrolytic Polishing Effect on Steel’s Surface Roughness after Cathodic Saturation with Nitrogen and Carbon

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.

Abstract The possibility of cathodic plasma electrolytic boriding of medium-carbon steel in an aqueous solution of ammonium chloride and boric acid followed by anodic plasma electrolytic polishing in an ammonium sulfate solution on the same equipment with a change in the operating voltage is shown. The morphology and roughness of the surface, microhardness of the modified layer have been investigated. Wear resistance was studied under dry friction conditions. It has been established that cathodic boriding at 850 °C for 5–30 min leads to the hardening of the surface layer up to 1050 HV with an increase in roughness by 1.5–2.5 times and wear resistance by 3.5 times. Subsequent anodic plasma electrolytic polishing of the boriding surface leads to a decrease in roughness with an increase in wear resistance by 2.3 times.
