Endothelial Cell Behavior and Nitric Oxide Production on a-C:H:SiO-Coated Ti-6Al-4V Substrate.

This paper focuses on the surface modification of the Ti-6Al-4V alloy substrate via a-C:H:SiO coating deposition. Research results concern the a-C:H:SiO coating structure, investigated using transmission electron microscopy and in vitro endothelization to study the coating. Based on the analysis of the atomic radial distribution function, a model is proposed for the atomic short-range order structure of the a-C:H:SiO coating, and chemical bonds (C-O, C-C, Si-C, Si-O, and Si-Si) are identified.
