“…Even though the use of TMZF for femoral stems has been discontinued, lessons learned can be applied to develop new alloys that provide improved tribocorrosion and fretting corrosion properties, decreased reduce stress shielding, and equal or better cyclic fatigue properties [14][15][16][17][18][19]. By doing so, it is of upmost importance to pay close attention to the implant alloy microstructure which can vary broadly even at the same chemical composition depending on the heat treatment and thermomechanical processing applied [20][21][22][23].…”

Current hip prostheses make extensive use of the aerospace alloy Ti-6Al-4V. This material was designed for aerospace applications but has far from ideal mechanical properties for biomedical applications, namely, a high elastic modulus and poor fatigue resistance. Moreover, its poor tribological properties are well known.However, beta, or near beta Ti alloys are known to have superior properties in that its elastic modulus is closer to that of bone coupled with a good fatigue resistance.Therefore, this work aims to analyse the tribocorrosion behaviour of 4 different titanium alloys (Ti-13Nb-13Zr, Ti-12Mo-6Zr-2Fe and Ti-29Nb-13Ta-4.6Zr aged at 300 o C and at 400 o C) at anodic potential, OCP and cathodic potential at 0.5N, 1N and 2N in bovine serum to identify the main cause of material degradation, the presence of a tribofilm and the synergism between corrosion and wear. The results show the alloys become more active when subjected to sliding in all conditions, but the material loss is lower at anodic potential. The alloys studied present a positive effect of corrosion on wear.

“…Guan et al investigated the corrosive behaviors of Cr doped DLC (a‐C:Cr) film in variable pH solutions and revealed that doping of Cr could result in good corrosion resistances due to presence of metallic chromium and chromic oxide. Moreover, there are many other studies related to tribocorrosion of various DLC films in various aggressive environments . While these studies have been of great utility, they pay much more attention to the anticorrosion performance of DLC films and the interaction effect between their corrosion and tribological behaviors, thus the dedicated tribological study in corrosive solutions for DLC films is weakened.…”

Tribological behaviors of three typical kinds of diamond-like carbon (DLC) films (a-C, a-C:Cr, and a-C:H) in sulfuric acid and sodium hydroxide solutions were investigated.The a-C film showed the lowest stable coefficients of friction (COF) in both sulfuric acid and sodium hydroxide solutions but the worst wear resistance in sulfuric acid solution. The a-C:H film showed the highest COF in sulfuric acid solution and the best wear resistance in both sulfuric acid and sodium hydroxide solutions. The a-C:Cr film exhibited superior comprehensive tribological performance in sulfuric acid solution, while in sodium hydroxide solution, high COF and very poor wear resistance was observed. What is more, friction and wear mechanism was revealed by investigating the friction-induced material evolutions on the sliding surface.

“…In M. Suzuki's study, water was reported to promote the formation of transfer film [8]. Inorganic salt ions can not only absorb on the friction surface, but penetrate into the film-substrate interface, which influences both friction and corrosion [9,10]. Biomolecules also can absorb on the friction surface and play an important role in the friction and wear behavior of DLC film in simulated body fluid [11,12].…”

A route to reducing the wear of the metal counterpart in the friction of meatal against diamond-like carbon (DLC) is to form a lubricating tribofilm on the metal counterface. However, in liquid lubricating conditions, the formation of tribofilm can be influenced by both the lubricating medium and the counterpart material. Here we report the effect of lubricating biomolecule and doping fluorine element on the formation of tribofilm in fluorinated DLC (FDLC)-Ti6Al4V friction system. A group of ball-on-disc frictional experiments with different sliding speeds and normal loads were performed in phosphate buffer solution (PBS) and bovine serum albumin (BSA) solution. The results showed the formation of tribofilm was inhibited by the absorption of biomolecules on the frictional surface, thus improving the friction coefficient and wear of Ti6Al4V counterpart. Doping fluorine into DLC film also can restrain the formation of tribofilm on Ti6Al4V counterface. As a result, tribofilm is difficult to form when Ti6Al4V counterface slides against FDLC in BSA solution. Fluorinated DLC film should be considered carefully for the anti-wear use in body fluid containing biomolecules because it might cause severe wear of the counterpart material.
