“…It is widely believed that film roughness exerts an important role in the COF. Generally speaking, a rougher film results in larger contact area and more asperity collisions [26]. Given that all surfaces were tested against Tungsten Carbide at 30 N load in dry air, 3 Hz frequency and 10 mm displacement.…”

Titanium (Ti) and its alloys as bio-implants have excellent biocompatibilities and osteogenic properties after modification of chemical composition and topography via various methods. The corrosion resistance of these modified materials is of great importance for changing oral system, while few researches have reported this point. Recently, oxidative corrosion induced by cellular metabolites has been well concerned. In this study, we explored the corrosion behaviors of four common materials (commercially pure Ti, cp-Ti; Sandblasting and acid etching-modified Ti, Ti-SLA; nanowires-modified Ti, Ti-NW; and zinc-containing nanowires-modified Ti, Ti-NW-Zn) with excellent biocompatibilities and osteogenic capacities under the macrophages induced-oxidizing microenvironment. The results showed that the materials immersed into a high oxidizing environment were more vulnerable to corrode. Meanwhile, different surfaces also showed various corrosion susceptibilities under oxidizing condition. Samples embed with zinc element exhibited more excellent corrosion resistance compared with other three surfaces exposure to excessive H 2 O 2 . Besides, we found that zinc-decorated Ti surfaces inhibited the adhesion and proliferation of macrophages on its surface and induced the M2 states of macrophages to better healing and tissue reconstruction. Most importantly, zinc-decorated Ti surfaces markedly increased the expressions of antioxidant enzyme relative genes in macrophages. It improved the oxidation microenvironment around the materials and further protected their properties. In summary, our results demonstrated that Ti-NW-Zn surfaces not only provided excellent corrosion resistance properties, but also inhibited the adhesion of macrophages. These aspects were necessary for maintaining osseointegration capacity and enhancing the corrosion resistance of Ti in numerous medical applications, particularly in dentistry.

“…They concluded that biofilms are responsible for a reduction in the coefficient of friction, although a localized decreasing of the pH is responsible for a decrease in the corrosion resistance of the surface. Ramos-Saenz et al [39] studied bone-implant contacts in thermally oxidized titanium alloys, which resulted in abrasion and adhesion wear mechanisms of these materials.…”

The growth of the dental implant market increases the concern regarding the quality, efficiency, and lifetime of dental implants. Titanium and its alloys are dominant materials in this field thanks to their high biocompatibility and corrosion resistance, but they possess a very low wear resistance. Besides problems related to osteointegration and bacterial infections, tribocorrosion phenomena being the simultaneous action between corrosion and wear, are likely to occur during the lifetime of the implant. Therefore, tribocorrosion resistant surfaces are needed to guarantee the preservation of dental implants. This work focused on the incorporation of magnesium, together with calcium and phosphorous, in the structure of titanium oxide films produced by micro-arc oxidation (MAO). The characterization of morphology, chemical composition, and crystalline structure of the surfaces provided important insights leading to 1) a better understanding of the oxide film growth mechanisms during the MAO treatment; and 2) a better awareness on the degradation process during tribocorrosion tests. The addition of magnesium was shown to support the formation of rutile which improves the tribocorrosion properties of the surfaces.

“…Hence the principal aim of this study is to understand the wear behavior and tribological properties of gamma-TiAl for reciprocatory sliding wear both in the unoxidized and oxidized conditions (at 500°C and 800°C) and under both dry and lubricated conditions, keeping in mind primarily implant applications. An earlier study characterized wear behavior for the above material using a novel bone pin made from a bovine femur [24] , where the wear was completely concentrated on the bone. In this study, a harder SS pin is used to produce wear in the oxide layer generated on gamma-TiAl.…”

Gamma titanium aluminide (gamma-TiAl) is a titanium alloy which contains no vanadium and appears to have potential for biomedical applications such as joint prostheses. The tribomechanical properties of Ti-48Al-2Cr-2Nb (at. %) (gammaTiAl) subjected to oxidation in air at 500°C and 800°C were determined by standard wear tests using a hardened stainless steel (SS) pin in a linearly reciprocating mode under both dry and lubricated (Ringer's solution) media. Similar properties for CP-Ti and Ti-6Al-4V were measured for comparison. The lowest mean mass loss was obtained for oxidized gamma-TiAl alloy indicating excellent wear resistance. The dominant wear mechanism on all the Ti alloy samples was abrasion. The oxidation temperature had a minimal effect on the wear of gamma-TiAl but was significant for the other two alloys.
