Abstracts

EN

The effects of the thermal cycles on the microstructures and properties of ductile iron modified by electrolytic plasma treatment were investigated. Microstructure changes occurring in the modified surface were characterized with scanning electron microscopy, X-ray diffractometry techniques. Martensitic structure evolved in the heat affected zone and ledeburite structure was produced in the molten zone of the ductile iron. Microhardness of the treated specimens improved considerably as compared to the original sample. X-ray diffraction clearly revealed the formation of a martensite phases in the modified zone.
