abstract = "Nanocrystalline (NCD) and/or microcrystalline (MCD) diamond films
grown on three-dimensional porous titanium (Ti) substrate were
obtained by hot filament chemical vapor deposition (HFCVD)
technique. The morphology variation of diamond films grown on
porous three-dimensional titanium substrate was studied at four
different deposition temperatures to investigate their influence
on nucleation density. Scanning electron microscopy images
depicted the continuous change from microcrystalline diamond
grains with a random crystallographic orientation, at 500 °C and
600 °C, to a cauliflower-like structure for deposits at 700 °C and
800 °C. Visible Raman spectroscopy confirmed the good quality of
diamond films and revealed that the amount of amorphous carbon
increased associated to the film morphology changes from MCD to
NCD. X-ray diffraction analyses, performed both through
{\`e}2{\`e} scans and at grazing incidence angle, allowed the
investigation of the crystallographic properties and structural
evolution of the different film/substrate interface phases, such
as TiC(111), TiC(200) and TiH2. The results revealed that the
temperature enhanced the nucleation sites for diamond growth.",
