“…Implant materials may need to endure high contact pressures (particularly load bearing implants, such as hip replacements), that are both cyclic and unpredictable, while in a severely corrosive solution containing high concentrations of ionic species, as well as organic and biological molecules which are capable of forming complexes with metallic species accelerating the corrosion [5]. In addition, wear debris can cause adverse biological reactions in the body, the material may be rejected by the immune system or the environment may have undesirable effects on material properties.…”

a b s t r a c tProduction of wear debris has been linked to the failure of numerous hip implants. With the current focus on increasing the implant longevity, thus wear and corrosion resistance is important. Hard coatings have the potential to reduce the wear and corrosion. Diamond like Carbon (DLC) coatings exhibit properties that could make them viable for implants. This paper critically reviews previously published research into usage of DLC coatings for implants. Overall DLCs seem to be an effective coating for implants but with the variance in results, further testing is required for clarification of use.

“…The influence of the biological species is also of great important. Studies have been carried out by the current authors and other research groups to understand the effect of proteins in synovial fluids on the tribological and corrosion properties of implant materials [15][16][17][18][19][20][21]. The effect of proteins on tribocorrosion is complicated and depends on the types of protein and tested materials.…”

Tribological problems and corrosion degradation have been recognized as essential risks for total joint replacements, especially for all-metal arthroplasty. Few studies have focused on the interactions between tribology and corrosion (tribocorrosion) for implant materials. This paper addresses the importance of understanding tribocorrosion and the evaluation of such materials in simulated biological environments. Due to the complex effect of proteins on tribocorrosion, which has been demonstrated in previous studies, this study focuses towards understanding the effects of amino acids as aspects of material degradation. Dulbecco's Modified Eagle's Medium (DMEM) is a cell culture solution. It contains comparable amount and types of amino acids to normal synovial fluid in human joints. 0.36% NaCl solution was employed to isolate the biological species. Three materials were tested; High carbon (HC) CoCrMo (contains 0.19% carbon), low carbon (LC) CoCrMo (widely used materials for total joint replacement) and stainless steel UNS S31603 (316L). Integrated electrochemical tests supported by measurement of friction and near surface chemical analysis were carried out to enable their tribocorrosion behaviour to be fully characterized. As a general conclusion, amino acids were found to react with materials under tribological contacts and form complex organometallic/oxides which lubricate the metallic sample surface. Tribocorrosion plays a very important role in material degradation in the studied environments. HC CoCrMo shows superior wear, corrosion and tribocorrosion resistance -the material characteristics and their effect on the different tribocorrosion processes are discussed.

“…The amino acids and proteins are adsorbed by metals 9,10) and sometimes accelerate the dissolution of metals. 11,12) Therefore, the alloys, whose surface has been characterized for the evaluation of the corrosion resistance and biocompatibility, are necessary to be exposed to the biological environment.…”

For the evaluation of zirconium-base amorphous alloys as biomaterials, the surface compositions of amorphous Zr-Al-Ni-Cu and Zr-AlCu alloys were characterized using X-ray photoelectron spectroscopy. The alloys were polished, autoclaved, and immersed in Hanks' solution or Eagle's minimum essential medium containing fetal bovine serum, MEM + FBS. Aluminum was enriched in the surface oxide film and the substrate just under the film of the alloys polished in water. After autoclaving, aluminum and copper were enriched in the substrate while zirconium was preferentially oxidized and incorporated into the surface oxide film. In Hanks' solution, copper and nickel decreased in the substrate and surface oxide film, resulting in the enrichment of aluminum in the substrate. In MEM + FBS, zirconium preferentially decreased by the effects of amino acids and proteins while copper was enriched in the substrate. The surface composition of zirconium-base amorphous alloys was much influenced by amino acids and proteins in MEM + FBS.
