Original abstract

The iron-rhodium alloy, having very interesting magnetic properties, is being studied for future use in next-gen data storage methods, for which high-speed information inscription is predicted. The examined material has been made by casting, but a for the purpose of examining its magnetic properties, the need for reducing the size of the sample arose. Because of this, wire electrical discharge machining method has been chosen, which allowed halving the sample while keeping the purity and surface properties of the original sample. This study is evaluating the morphology of the cut using electron microscopy, including microanalysis of chemical composition of the sample. Profile and area parameters were also studied, which define quality of the machined surface.

Czech abstract

Slitina železa a rhodia je díky svým magnetickým schopnostem zkoumána z důvodu budoucího využití v oblasti konstrukce nové generace paměťových médií, u nichž je predikována vysoká rychlost zápisu dat. Zkoumaný vzorek byl vyroben odléváním, přičemž z důvodu zkoumání jeho magnetických vlastností vznikl požadavek na redukci jeho tloušťky. Z tohoto důvodu byla zvolena technologie elektroerozivního drátového řezání, která umožnila rozpůlení vzorku s požadavkem na co nejmenší kontaminaci a ovlivnění povrchu vzorku. Studie se zabývá vyhodnocením morfologie povrchu řezu pomocí elektronové mikroskopie, včetně mikroanalýzy chemického složení. Dále byly zkoumány plošné a profilové parametry, definující jakost obrobené plochy.
