“…The minimum load (60 mN, 1.13 GPa max normal stress) and the maximum wear rate (850mN, 2.72 GPa max normal stress) gave wear values of 5.2×10 −9 and 3.25×10 −7 mm 3 /Nm, respectively. Extensive studies have been carried out to investigate wear rate of different types of diamond on diamond contacts [20–26]. For polycrystalline diamond film, it is reported that as-grown CVD polycrystalline diamond has a high wear rate value of approximately 4–5×10 −7 mm 3 /Nm with the normal stress of 1.1 GPa [25,26], and it can be decreased to 2×10 −9 mm 3 /Nm by means of mechanical polishing of diamond films [26].…”

Undoped and boron-doped nanocrystalline (NCD) diamond films were deposited on mirror polished Ti-6Al-4V substrates in a Microwave Plasma Assisted Chemical Vapor Deposition system. Sliding wear tests were conducted in ambient air with a nanotribometer. A systematic study of the tribological properties for both undoped and boron-doped NCD films were carried out. It was found for diamond/ diamond sliding, coefficient of friction decreases with increasing normal loads. It was also found that the wear rate of boron-doped NCD films is about 10 times higher than that of undoped films. A wear rate of ~5.2×10 −9 mm 3 /Nm was found for undoped NCD films. This value is comparable to the best known value of that of polished polycrystalline diamond films. Although no surface deformation, film delamination or micro-cracking were observed for undoped films, boron-doped NCD film undergoes a critical failure at a normal stress of 2.2 GPa, above which surface deformation is evident. Combined with high hardness and modulus, tunable conductivity and improved open air thermal stability, boron-doped nanocrystalline diamond film has tremendous potentials for applications such as Atomic Force Microscope probes, Micro-Electro-Mechanical System devices and biomedical sensors.

“…9,10 Both problems can be overcome by depositing at moderate temperature, about 600°C, fine-grained diamond ͑FGD͒ coatings with a very smooth surface finish. 6,11,12 Pure diamond is known to exhibit exceptional structural and physical properties and these have motivated an increasing number of studies. Diamond is characterized by a high refractive index, by the largest elastic constant values and by its low friction coefficient.…”

They were deposited on a titanium alloy by a two-step microwave plasma-assisted chemical vapor deposition process at 600°C. Their morphology and roughness were studied by scanning electron microscopy and atomic force microscopy. Their refractive indices were determined by the M-line spectroscopy technique. The diamond purity of all these coatings in terms of the sp 3 bonding fraction was deduced from visible and UV Raman spectroscopy as a function of the deposition conditions. All the samples were found to be textured with a ͗011͘ crystallographic direction normal to the film plane, leading to essentially hexagonal symmetry of the elastic tensor. By taking advantage of the detection of a number of different acoustic modes, complete elastic characterization of the films was achieved. The elastic constants C 11 and C 66 , respectively, were selectively determined from the frequency of the longitudinal and shear horizontal bulk modes traveling parallel to the film surface. The three remaining elastic constants, namely, C 44 , C 33 and C 13 , were obtained from detection of the Rayleigh surface wave a bulk shear wave and the bulk longitudinal wave propagating at different angles from the normal to the surface. The values of the elastic constants depend on the deposition conditions and on the microstructural properties of the films, especially the diamond quality and the polycrystalline or smooth fine-grained nature of the diamond. For the polycrystalline diamond film with the best quality, the elastic constants are rather close to the Voigt or Reuss average estimate values using known bulk elastic constants of diamond, whereas those of the smooth fine-grained diamond films are reduced because of the poorer diamond quality leading to lower residual stress in the films.
