ИСПОЛЬЗОВАНИЕ ВЫСОКОВОЛЬТНОГО ИМПУЛЬСНОГО РАЗРЯДА В ПРОЦЕССАХ УДАЛЕНИЯ МЕТАЛЛОВ-КАТАЛИЗАТОРОВ ИЗ АЛМАЗНЫХ СПЕКОВ

Аннотация

In the paper the possibility of electrodischarge processing is studied with the purpose of intensifi- cation of process of dissolution of metallical catalysts which are included in a structure of synthetic diamond. It has been shown, that in this case replacement of strong solutions of acids for ecological more harmless solution of ammonium nitrate is possible. With usage of a methods of a raster submicroscopy and photometric analysis the satisfactory condition of diamond after electrodicharge treatment and practical full deleting of metals - catalysts were demonstrated. The existence of synergistic effect at combined using of a chemical reactant and electrodischarge treatment upon metal components diamond has been supposed.
