Paper Abstract

The experimental samples, coated with buckyballs and buckytubes respectively, were processed with laser and subsequent quenching. Scanning electron microscopy, transmission electron microscopy, x-ray diffraction and Raman spectroscopy were employed to investigate the treated surfaces. The experimental results showed that diamond particles dispersed in Fe-C alloy system could be obtained by CO2 continuous laser-induced quenching of fullerene coatings on carbon steel s well as on ductile iron. The results also indicated that the treated surfaces, which reached an average macro-hardness of HRC 65-70, contained a great deal of polygonal crystallites on the order of microns and most of them were well-faceted cubic diamonds.
