| Abstract: | Low-temperature method for depositing ultra fine diamond (UFD) films by
a simple wet chemical route is presented. The UFD is produced from detonation
synthesis of explosive substances. These nano-sized diamond particles under
specific conditions formed stable suspension with analogous properties as sols.
The organic suspensions of UFD had low values of surface tension and could
easily wet different substrates to form films by dipping technique. The surface
of the substrates and the effects of the organic medium stimulated a structural
organization. The action of different forces during wetting caused the
desegregation of particles, which culminated in even distribution on the
substrate. The spectral investigation in UV-VIS-IR region showed that the films
had diamond-like optical properties. It was found that glasses became more
transparent with these UFD coatings on them. Efficiency of cutting tools was
also found to increase significantly with the use of UFD coating on them. |
