Optimization of saturating mixture compositions has been carried out in two three-component systems, namely: Cr-Ti-V and Cr-Ti-Mn in respect of micro-hardness and wear resistance of carbide coatings obtained by thermo-chemical treatment of high carbon steel. «Composition properties» diagrams have been plotted using mathematical models. Treatment with optimum compositions of powder media permits to increase wear resistance of steel by factor of 30-70 as compared with untreated steel.
Проведена оптимизация составов насыщающих смесей в двух трехкомпонентных системах Сr-Ti-V и Сr-Ti-Mn по микротвердости и износостойкости карбидных слоев, полученных путем химико-термической обработки высокоуглеродистой стали. С помощью математических моделей построены диаграммы «состав - свойство». Обработка в оптимальных составах порошковых сред позволяет увеличить износостойкость стали в 30-70 раз по сравнению с необработанной сталью.
