| Popis: | The paper addresses findings regarding the influence of electrolytic plasma treatment on the mechanical properties as well as structural and phase states of × 12 CrNi 18 10 Ti steel. Electrolytic plasma treatment is based on carburizing of stainless steel heated in electrolytes. Treatment of steel samples has been performed as follows: the samples were heated up to a temperature between 850 and 950 °C and then they were cured for 7 minutes in an electrolyte of an aqueous solution containing 10 % glycerol (C3H8O3) and 15 % sodium carbonate (Na2CO3). It is found that, after plasma electrolytic treatment, the surface of × 12 CrNi 18 10 Ti steel had a modified structure and high hardness. Increasing wear resistance of × 12 CrNi 18 10 Ti steel has been observed after carburizing and the coefficient of friction has been reduced. X-ray analysis showed that retained austenite γ-Fe is a main phase, and there are some diffraction lines of orthorhombic Fe3C phase as well as Fe3O4 cubic phase. It has been de... |
