Microcosmic analysis of amino group implanted titanium / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>The purpose of this study was to determine the effects of amino group implantation on the surface structures of titanium.</p><p><b>METHODS</b>The amino groups were implanted into the surfaces of titanium using 100 keV amino group ions at ambient temperature (25 degrees C) with the following three different doses 5 x 10(17), 1 x 10(17) and 5 x 10(16) ions per cm2. The current density of the ion-beam was (10 microA/cm2. The modified surfaces were characterized using X-ray photoelectron spectroscopy (XPS) to determine the chemical components of the modified surfaces. A scanning electron microscope (SEM) was used to study the physical structure of the surfaces.</p><p><b>RESULTS</b>The wide XPS profiles, the binding energy data and the SEM photos were obtained. The XPS showed that the modified surface contained Ti, O, C and N. The possible chemical states were speculated using Gauss matching analysis. There was no significant difference between the surfaces with and without implanted amino groups.</p><p><b>CONCLUSION</b>The XPS data reveals that the structure of the modified surface layer of aminogroup-implanted titanium is TiN, comprising a complex structure of titanium and amino compound near the surface. The SEM Photos show that this technique has little effect on the surface structures of materials.</p>
