STRESZCZENIE: Przedstawiono krótko analizę modyfikowania siluminu z zastosowaniem metody EDA. Warstwa wierzchnia była modyfikowana w procesie obróbki elektroerozyjnej za pomocą elektrody kompozytowej wykonanej ze spieku Fe-WC. Wykonano podstawowe badania metalograficzne oraz EDS naniesionej warstwy. Na tej podstawie określono skuteczność przenoszenie się składników stopowych z elektrody do materiału modyfikowanego.
SŁOWA KLUCZOWE: EDM, EDA, warstwa wierzchnia
ABSTRACT: The article presents a brief analysis of the deposition layer using EDA. The surface layer was modified using electrodes Fe - WC on the machine electro-erosion. The layer was tested by metallographic methods and EDS. There were identified on the basis of which the transmission of alloying elements from the electrode to the weld overlay.
KEYWORDS: surface layer, spark deposition, EDM, coating
