Use of nanostructured materials in implants

Nanobiomaterials

Metallic implants such as hip and knee often fail due to the combined action of wear and corrosion. Nanocrystalline diamond (NCD) coatings on metallic implants can be a potential candidate to overcome this issue. In this work, we investigated the tribocorrosion and electrochemical behaviour of Nanocrystalline Diamond (NCD) Coatings deposited on Cp-Ti, Ti-6Al-4V and Ti-13Nb-13Zr using hot filament chemical vapour deposition (HFCVD) technique. The results demonstrate that the factors such as intercrystallite pores, TiC interlayer, and electrical conductivity influenced the electrochemical behaviour of all the NCD coatings. Under tribocorrosion, an unexplainable shift in the open circuit potential (OCP) was noticed at the initiation of sliding. Further, a continuous decrease in OCP was also observed as the sliding progress. © 2016 Elsevier Ltd

Tribocorrosion and electrochemical behaviour of nanocrystalline diamond coated Ti based alloys for orthopaedic application

The field of biomaterials has become a vital area, as these materials can enhance the quality and longevity of human life and the science and technology associated with this field has now led to multi-million dollar business. The paper focuses its attention mainly on titanium-based alloys, even though there exists biomaterials made up of ceramics, polymers and composite materials. The paper discusses the biomechanical compatibility of many metallic materials and it brings out the overall superiority of Ti based alloys, even though it is costlier. As it is well known that a good biomaterial should possess the fundamental properties such as better mechanical and biological compatibility and enhanced wear and corrosion resistance in biological environment, the paper discusses the influence of alloy chemistry, thermomechanical processing and surface condition on these properties. In addition, this paper also discusses in detail the various surface modification techniques to achieve superior biocompatibility, higher wear and corrosion resistance. Overall, an attempt has been made to bring out the current scenario of Ti based materials for biomedical applications.
