In Vitro Biodegradation of a-C:H:SiO_x Films on Ti-6Al-4V Alloy.

ABSTRACT: This paper focuses mainly on the in vitro study of a five-week biodegradation of a-C:H:SiO_x films of different thickness, obtained by plasma-assisted chemical vapor deposition onto Ti-6Al-4V alloy substrate using its pulsed bipolar biasing. In vitro immersion of a-C:H:SiO_x films in a solution of 0.9% NaCl was used. It is shown how the a-C:H:SiO_x film thickness (0.5-3 µm) affects the surface morphology, adhesive strength, and Na⁺ and Cl^- precipitation on the film surface from the NaCl solution. With increasing film thickness, the roughness indices are reducing a little. The adhesive strength of the a-C:H:SiO_x films to metal substrate corresponds to quality HF1 (0.5 µm in thickness) and HF2-HF3 (1.5-3 µm in thickness) of the R
