摘要：
Smooth, fine-grained diamond coatings have been deposited on titanium alloy by a two-step microwave PACVD process at 600 degreesC. Their morphology and roughness were studied by scanning electron microscopy and atomic force microscopy in comparison with polycrystalline coatings. The diamond purity of all these coatings in terms of sp(3) bonding fraction was deduced from visible and UV Raman spectroscopy as a function of the deposition conditions. Finally, the influence of diamond purity on hardness, Young's modulus and residual stresses of the coatings are reported. (C) 2001 Elsevier Science B.V. All rights reserved.
