“…From the C 1s spectra, it was concluded that none of the specimens contained carbonate because no peak was detected at an energy region of 289-290 eV, where carbonate should give a C 1s peak. 25) Therefore, the carbon detected by XPS can be ascribed to a so-called contaminant carbon. Apart from carbon, only titanium, aluminum, and oxygen were detected with XPS in specimens abraded in water.…”

Titanium and some of its alloys are successfully used for biomaterials. The surface oxide films on these materials play important roles in maintaining corrosion resistance and biocompatibility. In this study, Ti-6Al-4V, Ti-56Ni, and Ti-xZr (x = 0, 25, 50, 60, 75, 100) alloys in mass% were abraded and kept for 300 s in water and Hanks' solution. The regenerated surface oxide film in Hanks' solution was characterized using X-ray photoelectron spectroscopy. As a result, phosphate ions were preferentially taken up in the surface oxide film during regeneration. Ions constituting Hanks' solution other than calcium and phosphate were absent from the surface oxide film. In the case of titanium and Ti6Al-4V, calcium phosphate was formed on/in the surface oxide film regenerated in Hanks' solution. However, Ti-56Ni, Ti-Zr, and zirconium did not form calcium phosphate on themselves but formed phosphate without calcium. These results are in good agreement with those for titanium alloys immersed in Hanks' solution.

Accelerated Calcium Phosphate Formation on Titanium Utilizing Galvanic Current between Titanium and Gold in Hanks’ Solution

To enhance hard-tissue compatibility of Ti, galvanic current between titanium (Ti) and gold (Au) may be available. Prior to the design of medical devices with the capability to generate a galvanic current, it is necessary to understand the control mechanism. In this study, we first measured galvanic current between Ti and Au with various surface areas in Hanks' solution. The galvanic current increased immediately after connection of two electrodes, followed by an abrupt decrease and a steady state. The galvanic current varied with the combinations of Ti and Au areas. We, thereafter, evaluated the formation of calcium phosphate on Ti under a condition of applying simulated galvanic current. Surface characterization was revealed in which the calcium phosphate formation was enhanced accompanied by growth of Ti oxide layer under the galvanic current application. A similar result was observed on Ti with patterned Au coating without outer electric power. Therefore, galvanic current is useful to enhance hard-tissue compatibility, and this technique has potential for applications to metallic biomaterials.

The objective of this study was to investigate the effect of active hydroxyl groups on a titanium (Ti) surface on the bond strength between Ti and segmented polyurethane (SPU) composite through γ-mercapto propyl trimethoxysilane (γ-MPS). Active hydroxyl groups on Ti surface oxide were controlled by immersion in hydrogen peroxide (H2O2) with different lengths of immersion time, and the resulting concentrations of active hydroxyl groups were evaluated using a zinc-complex substitution technique. For the H2O2-treated Ti, it was characterized using X-ray photoelectron spectroscopy and scanning electron spectroscopy. For the bond strength of Ti/γ-MPS/SPU interface, it was determined using a shear bond test. Results showed that the bond strength increased with increase in the concentration of active hydroxyl groups. In terms of durability after immersion in water at 310 K for 30 days, it was found that bond strength was improved with increase in active hydroxyl groups. Based on the results obtained, active hydroxyl groups on the surface oxide film were clearly one of the causes governing the interfacial bond strength.
