陽極酸化と水熱処理によりTi表面に析出するハイドロキシアパタイト皮膜の解析

抄録

The thin HA layer that was deposited by anode oxidation and hydrothermal treatment (SA treatment) on a titanium surface, was called by a SA film.
It was suggested that the SA film was reported exhibiting bone conduction, long term stability and high adhesion strength with a titanium substrate by a study result in vivo and in vitro.
The purpose of this study was to examine the shape and crystal structure of HA in a SA film by SEM, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS).
An anodic oxide film, SA film and comparison matter were measured by SEM, XRD, XPS.

From SEM and XRD, it was made clear that HA of a hexagonal system deposition on a SA film and three layers of SA film presented structure.
In the examination by XPS, the anodic oxide film moved to the low energy side and the SA film moved to the high energy side compared with HA of the comparison matter.
By XPS, it became clear that a SA film formed HA of higher crystallization than HA.
