摘要：

Recently, attention has been focused upon the growth of diamond on diamond crystals (surface recrystallization) at atmospheric pressure in an NaOH-Ni-C system. In this paper, we have investigated the deposits obtained on high pressure, high temperature synthetic diamond crystals and Ni substrates. Examination of the carbon deposits on diamond crystals by scanning electron microscopy shows that the deposition is strongly affected by the synthesis conditions. The deposited layer grows epitaxially on the diamond crystals. The solidified melt has been analysed by IR spectrometry, X-ray diffraction and emission spectroscopy. Specific IR lines were observed. NiO, Na2CO3 and gamma-NiO(OH) were involved in the growth process.
