Abstract
Abstract Deposition of smooth diamond coatings on titanium alloy. A new process has been perfected to deposit smooth diamond coatings, at 600 °C, on titanium alloys. Scanning electron microscopy, X-ray diffraction, visible and UV Raman spectroscopy show that these coatings are smooth and mainly composed of crystalline diamond with a fine-grained morphology. The results are compared here to those obtained with classical rough polycrystalline coatings. Optical emission spectroscopy reveals important differences between the plasma species produced for the deposition of these smooth coatings and the plasma species produced for the deposition of both polycrystalline diamond and nanocrystalline films. © 2000 Academie des sciences / Editions scientifiques et medicales Elsevier SAS diamond / coating / titanium alloy / plasma / roughness / Raman spectroscopy / emission spectroscopy
