“…Generally, the function group of C-C and C-O were non-polar, showing more hydrophobic than the polar function group of C=O. 13) Although the shapes of C 1s before and after oxidation were almost the same, more hydroxide than oxide was detected before air oxidation, while more oxide than hydroxide was detected after air oxidation. Almost no Cr 0 peak was detected after oxidation.…”

The surface compositions and morphologies of pure chromium after wet polishing, air oxidation and further micro-wetting by distilled water, were investigated with X-ray photoelectron spectroscopy (XPS) and the AC non-contact mode of atomic force microscope (AFM). An organic contaminants/water layer on the chromium oxide/hydroxide layer, was detected by XPS analysis for each surface. The oxide/hydroxide layer became thicker, and the oxide : hydroxide ratio increased, after air oxidation. In ambient air, the AFM showed a thin liquid layer on each surface, which was easily moved by the cantilever of the AFM and can be condensed or evaporated. The inner part of the liquid might be adsorbed water, and the outer part is thought to be organic contaminants since the liquid did not combine with distilled water applied by postwetting. Micro-droplets of distilled water deposited by post-wetting always occupied positions without or with little of this liquid, which might explain the obtained higher micro-than macro-wettability.

“…A careful analysis of the C1s line shows that no shift of the maximum does occur upon storage ( figure 9), but for the samples stored in polystyrene the intensity increases weakly in the region of 288.5eV. In case of airborne contamination, this is generally identified as a contribution from -COO bonds [33]. In conclusion both, hydroxyls groups and hydrocarbons with -COO bonds adsorb on the surface during storage in polystyrene, whereas almost no change is observed for the sample stored wrapped in aluminum foil.…”

“…3), because the presence of P is too small to be assigned to the P = O-bond (531.3 eV) ( Table 2). The high resolution C1s spectrum can be resolved in three peaks: one at 284.8 eV representing carbons in a hydrocarbon environment (C-C, C-H) and the others at 286.3 and 288.4 eV representing carbons in C =O and O-C = O bond (Mantel and Wightman, 1994).

“…The high resolution C1s spectrum shows a broadening with a contribution of three different components corresponding to carbon in different environments: the first peak, at the lowest binding energy, is assigned to carbon bonded to C or H (C-C, C-H groups); the second peak is attributed to carbon in C=O bond and the third peak, at the highest binding energy, includes the signal for carbon in O-C=O (Mantel and Wightman, 1994) (Fig. 3; Table 2).…”

“…BSA is able to reduce significantly the resistance of the oxide layer maybe due to the organometallic complex formation. Nevertheless, in literature has been published that these ions could remove BSA molecules, adsorb on the surface and form CaP deposits but at longer times (Mantel and Wightman, 1994).…”

ABSTRACT:The study of the interaction between the thermally treated Ti (TT-Ti) at 277 °C for 5 hours and the body fluids, ranging from the simplest to the most complex solution is analysed. Electrochemical techniques such as the measurement of the corrosion potential, electrochemical impedance spectroscopy and the polarization curves have been used. The characterization of TT-Ti has been performed by scanning electron microscopy, atomic force microscopy and X-ray Photoelectron Spectroscopy (XPS). The XPS reveals that the peak intensity associated with phosphate and calcium increases as immersion time does. However, the albumin covers rapidly the surface since the C peak intensity remains constant from the first day to the end of immersion time. The calcium ions have a bridging effect on the electrostatic adsorption of phosphate ions as well as that of albumin and the acidic hydroxyl groups of the oxide layer. The impedance measurement shows that the resistance of the oxide layer immersed in albumin and foetal bovine serum decrease probably due to the formation of organometallic complex. The polarization curves reveal that the presence of proteins decreases the current of anodic branch indicating that the proteins work as a barrier on the surface. RESUMEN: Interacción de compuestos inorgánicos y orgánicos de fluidos fisiológicos con superficies de Ti tratadas térmicamente.Se estudia la interacción del Ti oxidado a 277 °C durante 5 horas con compuestos orgá-nicos e inorgánicos presentes en los fluidos fisiológicos, desde la solución más simple a la más compleja. Se han utilizado técnicas electroquímicas como la evolución del potencial de corrosión, espectroscopía de impedancia electroquímica y curvas de polarización, y la espectroscopía de fotoelectrones de rayos X (XPS). El XPS revela que la intensidad de los picos asociados a los iones fosfato y calcio aumenta con el tiempo de inmersión. Sin embargo, la albúmina cubre desde el primer día la superficie, ya que la intensidad de los picos asociados a la presencia de C permanece prácticamente constante hasta el final del ensayo. Los iones calcio actúan como puente de unión entre los iones fosfato y la albúmina, y los grupos hidroxilo ácidos de la capa de óxido. Las medidas de impedancia muestran que la resistencia de la capa de óxido en albúmina y FBS disminuye probablemente debido a la formación de complejos órgano-metálicos. Las curvas de polarización revelan que cuando la solución contiene proteínas, la intensidad de la rama anódica disminuye indicando que las proteínas ejercen un efecto barrera sobre la superficie del Ti.
