PL W pracy przedstawiono autorski opis procesu powstawania powierzchniowej warstwy stopowej, którego istota opiera się na dyfuzji w stanie stałym węgla i chromu z wkładki w stronę staliwa w obrębie ziaren FeCrC, jak również na dyfuzji w warstwie ciekłego żeliwa chromowego powstałego w wcześniejszych et[...]
EN A description of alloy layer formation on a steel substrate is presented. Two types of formation are considered: diffusion of carbon and chromium into the solid from the pad in the direction of the cast steel within the FeCrC (grains) and diffusion in a layer of liquid chromium cast iron formed in a[...]

PL W pracy przedstawiono metodę poprawy własności użytkowych odlewów ze staliwa niestopowego w wyniku dyfuzji C i Cr występującej w procesie wytwarzania warstwy wierzchniej. Zasadniczym celem badań było określenie zasięgu dyfuzji podstawowych składników wierzchniej warstwy stopowej. Badania obejmowały [...]
EN In paper a method of improvement in utility properties of unalloyed cast steel casting in result of diffusion of C and Cr in process of creation of surface layer is presented. The aim of paper was determination of diffusion range of basic elements of alloyed surface layer. Moreover a quantitative an[...]
