INFLUENCE OF COPPER SUBLAYER ON NUCLEATION OF DIAMOND CRYSTALS ON SURFACE OF TUNGSTEN CARBIDE

The buffer copper sublayer on the surface of tungsten carbide was obtained with the chemical deposition from aqeous solutions. With the using the methods of SEM, AFM, XRF it was established that at temperature of 23 °C the layer structure is porous that do not ob-served at negative temperatures. The sublayer structure influences the character of nuclea-tion of diamond crystals and their form. The phase composition was determined with Raman spectroscopy. The spectrum shows the lines of diamond (1334 cm-1), sp2 of carbon and trans-polyacetylene (1170 сm-1).

Key words: copper sublayer, diamond film, tungsten carbide, cryochemical processing
