Titanium Oxide (TiO{sub}2) Coatings Produced on Titanium by Oxygen-Plasma Immersion and Cell Behaviour on TiO{sub}2

摘要

Plasma immersion process was investigated as a method for producing bioceramics coatings on metallic implants due to its advantages, which include the production of coatings on three-dimensional workpieces, with high density and superior adhesion. In this process, the oxygen plasma was utilized to form titanium oxide on titanium substrate. The structure, composition and surface morphology were studied using scanning electron microscopy (SEM) and X-ray diffraction. In addition a preliminary study has also been carried out, on TiO{sub}2-coated and uncoated titanium substrates, to analyse the in vitro biocompatibility (cytotoxicity evaluation and cell morphology).
