摘要：

Thin films of diamond-like carbon (DLC) containing titanium oxide (DLC-TiO(x), x <= 2) were synthesized using a pulsed DC metal-organic plasma activated chemical vapor deposition (MOCVD) technique. X-ray photoelectron spectroscopy (XPS) results confirmed the presence of TiO(2) on the surface of the films. The compressive stress, elastic modulus and hardness of the films decreased with increasing Ti content. The water contact angle reduced from 62 degrees for DLC to 45 degrees for DLC-TiO(x) films containing 13.3 at.% of Ti. The biomimetic growth of amorphous carbonated apatite on the DLC-TiO(x) in simulated body fluid (SBF) was found and dependent on the Ti content of the film. UV light exposure prior to immersion in SBF increased the growth rate of apatite formation significantly as a result of increased hydrophilicity of the surface. (C) 2009 Elsevier B.V.
