“…Such observation was recently reported in the experiment performed by Patel et al [83] where they concluded that after insertion of anodized Ti6Al4V rods into simulant bone, loose debris or particulates of simulant bone were accumulated on the surface. Rutile is characterized by improved corrosion resistance as compared to anatase phase [52,90]. Furthermore, it is also reported in literature the formation of well-adherent rutile TiO 2 phase on cp-Ti with improved wear resistance and reduced friction coefficient [3].…”

“…Then the cells were dehydrated in graded alcohols (70, 80, 90 and 100 %) for 10 min each. To simulate the critical point drying, solutions of hexamethyldisilazane (HMDS, Sigma-Aldrich, USA) in alcohol (50,60,70,90, and 100 %) were progressively added to materials, during 10 min each. The materials were sputter-coated with gold and analyzed by SEM.…”

Titanium (Ti) dental implants are frequently exposed simultaneously to a corrosive environment and cyclic micromovements at implant/abutment and implant/ bone interfaces, becoming part of a tribocorrosion system. Thus, wear debris and corrosion products/ions can be released to peri-implant tissues and induce inflammatory reactions leading to implant failure. Moreover, the poor osseointegration is also one of the main problems affecting dental implants lifetime. Surface modification strategies have been proposed to design novel Ti oxide-based multifunctional surfaces that are able to simultaneously improve cellular functions and provide enhanced tribocorrosion resistance. Hence, the main objective of this work was the synthesis of Calcium (Ca)-and Phosphorous (P)-enriched Ti oxide films aimed to display superior wear/corrosion performance and simultaneously, to enhance osteoblast-material interactions. Ca-and P-enriched films were synthesized by plasma electrolytic oxidation (PEO) and their characteristics were assessed by Field emission scanning electron microscopy, profilometry, energy-dispersive X-ray spectroscopy, X-ray diffraction, and water contact angle measurements. PEO-treated samples were subjected to pin-on-disk reciprocating sliding tests in artificial saliva at 37°C. The viability of MG63 cells cultured on PEO-treated samples was investigated by MTT assay, and their adhesion ability by SEM and confocal laser scanning microscopy. The wear/corrosion behavior of Ti was improved after PEO treatments and the electrolyte composition appeared to play a crucial role both on its corrosion tendency and mechanical wear resistance. It is believed that this improvement is related to the higher rutile/anatase ratio exhibited by Ca-and P-enriched surfaces. Osteoblasts were well spread on these surfaces displaying improved viability/proliferation compared to Ti.

“…The slightly different morphologies of TiO 2 and B-TiO 2 films are related to the MAO process. As the addition of Na 2 B 4 O 7 Á 10H 2 O enhances the electric conductivity of the electrolyte, it increases the partial voltage on the film surface and consequently leads to more intense breakdown of the oxide film to some extent [21]. However, the surface morphologies of MAO-fabricated films are not quite different.…”

“…The high-energy resolved XPS Ca 2p, Ti 2p, Si 2p and O 1s spectra of treated Ti alloys are presented in Figure 7a-d. The binding energy of XPS Ca 2p 3/2 peak (at 347.0 eV) is found to be the same for all three alloys and corresponds to the Ca-O bond of CaSiO3 [37]. The XPS Si 2p peak position could be well fitted at 102.0 eV, relating to Si 2p in CaSiO3, but different from that of SiO2 (at 103.3 eV).…”

Abstract:The surface modification of titanium alloys is an effective method to improve their biocompatibility and tailor the material to the desired profile of implant functionality. In this work, technologically-advanced titanium alloys-Ti-15Mo, Ti-13Nb-13Zr and Ti-6Al-7Nb-were anodized in suspensions, followed by treatment in alkali solutions, with wollastonite deposition from the powder phase suspended in solution. The anodized samples were immersed in NaOH or KOH solution with various concentrations with a different set of temperatures and exposure times. Based on their morphologies (observed by scanning electron microscope), the selected samples were investigated by Raman and X-ray photoelectron spectroscopy (XPS). Titaniate compounds were formed on the previously anodized titanium surfaces. The surface wettability significantly decreased, mainly on the modified Ti-15Mo alloy surface. Titanium alloy compounds had an influence on the results of the titanium alloys' surface modification, which caused the surfaces to exhibit differential physical properties. In this paper, we present the influence of the anodization procedure on alkali treatment effects and the properties of obtained hybrid coatings.
