“…In recent years, there has been a growing demand for artificial implants to address human dysfunction caused by an aging population and major diseases. − Cr–Co–Mo, 316L stainless steel, and titanium alloy (Ti6Al4V), the bio-inert metal alloys, are used as implants for various medical applications. − Ti6Al4V alloys are now the most attractive metal materials for biomedical applications, which are attributed to their low density, high specific strength, high biocompatibility, and chemical stability . In medicine, they are used to implant devices to replace failing hard tissues, such as artificial hips, knee joints, bone plates, fracture fixation screws, etc. − However, human body fluids are an extremely harsh environment, , which contains many corrosive ions, such as chloride ions. In addition, the tribological performances of Ti6Al4V are poor.…”

Ti6Al4V artificial implants are increasingly demanded for addressing human dysfunction caused by an aging population and major diseases. However, they are restricted due to the release of vanadium and aluminum ions in the process of corrosion and wear. This work is aimed to provide a protective film for Ti6Al4V artificial implants, and then, a Si-incorporated diamond-like carbon (Si-DLC) film and Si-and N-incorporated DLC (SiN-DLC) film were deposited on the surface of Ti6Al4V by plasma-enhanced chemical vapor deposition. Results suggest that the thickness of the as-deposited DLC film is approximately 2 μm, and the SiN-DLC film shows the lowest surface roughness (53.0 ± 3.6 nm) compared with the Ti6Al4V and DLC films. The above DLC film possesses high mechanical properties compared with Ti6Al4V, and the SiN-DLC film shows the best resistance to plastic deformation. In addition, the DLC film exhibits high adhesive strength (>13 N) with Ti6Al4V, which is a prerequisite for service in liquid environments. Whether in SBF solution or SBF + BSA solution, the friction coefficient and wear rate of the above DLC film are much lower than those of Ti6Al4V, and the SiN-DLC film displays the optimal tribological properties (0.072 and 1.82 × 10 −7 mm 3 •N −1 •m −1 , respectively). Moreover, Si-DLC and SiN-DLC films possess similar corrosion resistance but are far better than Ti6Al4V. Cytotoxicity test results show that the SiN-DLC film can significantly improve cell viability and promote cell proliferation to a certain extent. Consequently, the SiN-DLC film is a protective film with more potential for artificial implants.

Under tribological conditions in aqueous medium, the contact of materials does involve some degradations of materials. Especially friction under small reciprocal displacement, i.e., fretting corrosion, is occurring; this topic has been highlighted since the 80′s regarding hip implants. Hip prosthesis is assembled from three parts: femoral stem, neck and head. Fretting corrosion or friction corrosion between metallic parts first involves some degradation of the oxides layers. This step is governed by mechanics and it is related to some few minutes. Afterwards the corrosion occurrs enhanced by mechanical degradation. As well focused some oxides and some metallic ions are related to biocompatibility issues. Some strategies are available in order to avoid metal against metal friction and/or fretting. Some hard coatings and some smooth coatings were investigated. The first one is diamond-like carbon (DLC), and the second is a polyetheretherketone (PEEK), polymeric one. The investigations were focused on fretting corrosion solicitations of Ti-6Al-4V vs. Ti-6Al-4V + coating. DLC as a coating delays the corrosion degradation. The PEEK coating does not promote any corrosion degradation of the metallic counter part and more generally any wear.

“…15 (g) , and it is evident that ZrO 2 was transferred to the alloy surface under the fretting motions according to the EDS results. Previously, Semetse et al[ 30 ] investigated the fretting-corrosion performance of Ti6Al4V enforced with ZrO 2 and also discovered the ZrO 2 particles on the counter body. It is believed that the detached hard debris would act as a third body and further scratch the counter surface, as in Fig.…”

“…Several efforts have been ongoing to investigate such equipment. For instance, Miyoshi et al [ 27 ]–[ 29 ] evaluated the behavior of alloys and composites under fretting conditions by using a sliding/fretting wear apparatus, Geringer et al[ 1 ], [ 2 ], [ 30 ] studied fretting-corrosion of orthopedic implant materials by a presented fretting device. Swaminathan et al [ 31 ] proposed a fretting-corrosion test system to study CoCrMo and Ti6Al4V interfaces, and Royhman et al [ 26 ] [ 32 ] designed a set-up and simulated fretting-corrosion in hip modular junctions.…”

Fretting-corrosion is one of the failure processes in many applications, including biomedical implants. For example, the modern design of hip implants with multiple components offers better flexibility and inventory storage. However, it will trigger the fretting at the implant interfaces with a small displacement amplitude (< 5 µm) and usually in a partial slip region. Although many studies have been reported on the fretting, they have high displacement amplitude and are in the gross slip region. It is imperative to have an apparatus to overcome such limitations, specifically for hip implant applications. Therefore, this study describes the development of a fretting-corrosion apparatus with low micro-motion (≤ 5 µm) that can simultaneously monitor the corrosion process. Initial experiments with Ti6Al4V-Ti6Al4V in 0.9% saline, Ti6Al4V-Ti6Al4V in bovine calf serum (BCS), and ZrO2-Ti6Al4V in BCS were conducted to validate the system. As a result, the fretting regime of all groups remained partially slip region throughout the 3600 cycles, and the possible failure mechanisms are proposed in this manuscript.
