AFM images of diamond films grown using microwave
plasma chemical vapor deposition. The film morphology can range from
highly crystalline with well-defined facets (left image) to a much
smoother nanostructured appearance with nanometer-sized diamond grains
and a significantly higher amorphous carbon content (right image).

Optical micrograph showing large indents made on a
nanostructured diamond-coated titanium alloy using a 1/8” diameter
tungsten carbide ball at loads of 30 kg, 60 kg, 100 kg, and 150 kg
(counter-clockwise from upper right). This test demonstrates the excellent
adhesion and toughness of the film since no delamination is observed.

Standing in front of our home-made 1.2 kilowatt
microwave plasma chemical vapor deposition system. This system has been
configured for in-situ monitoring of film thickness using Laser
Reflectance Interferometry (LRI) and of excited state gas-phase species
using Optical Emission Spectroscopy (OES). |
