Ionic Oxidation in Cathodic Cage of Titanium CP Grade II

Abstract

Titanium oxides such as rutile and anatase, are materials that stand out for exhibiting properties that act in biomedical and photocatalytic applications, among others. It is extreme importance to idealize new techniques that produce such compounds, being indispensable the improvement of characterizations for these materials. For this purpose, titanium comercially pure (CP) grade II cylindrical samples were oxidized ionically using titanium cage electric shields, oxidized at 350 ° C in 3 and 8 hours. Through Grazing Incidence X-ray Diffraction (GIXRD) analysis, was observed on the surface of the treated samples the formation of a TiO 2 film with the anatase, rutile and brookite phases, the latter phase cited being difficult to produce in conventional thermochemical treatments. All samples treated showed a significant increase in wettability using distilled water. The higer value was for the sample with a 8 hours treatment time, in which this condition presented phases with greater intensity in the analysis of GIXRD.

Synthesis of TiN and TiO2 thin films by cathodic cage plasma deposition: a brief review

“…The microstructural images showed an increase in the thickness of coating with an increase in processing time. In 2017, Vitoriano et al [76] carried out the oxidation of titanium (commercially pure grade II) assisted with titanium cathodic cage. They reported the formation of titanium dioxide coating with anatase, brookite, and rutile phase, and enhancement in wettability after titanium oxide coating.…”
