Characterization of bioactive ceramic coatings prepared on titanium implants by micro-arc oxidation

Titanium oxide films were obtained by MAO at the applied voltages of 250-550V and their bio-mineralization behavior was investigated. The films were composed mainly of TiO2 phases in the form of anatase and rutile and enriched with Ca and P elements in the form of CaTiO3 and amorphous calcium phosphate. Their bio-mineralization behavior was evaluated in a simulated body fluid (SBF). After immersed in SBF for 72 h, white mineralized layers were observed on the samples obtained at high voltages. The bio-mineralized rate of samples increased with the applied voltages, which resulted in the difference on morphology of different samples. The structure and composition of the films have an important effect on their bio-mineralization behavior.

ZL114 aluminum alloy samples were treated by micro-arc oxidation using alkaline solution added different amount of nano-Al2O3to improve the surface properties. Effects of the additives were investigated by thickness, hardness, morphologies and corrosion performance. The results indicated that proper amount of nano-Al2O3had certain contribution with higher corrosion performance. And adding too much nano-Al2O3decreased the property of ceramic coatings.

Bioceramic Coatings

With age bones lose quality being in some cases necessary their replacement. Research is underway on the development of biomaterials to meet the mechanical and biological requirements. One of the most used alloys is Ti6Al4V. The disadvantage of this biomaterial is the formation of a layer of connective tissue between the implant and the surrounding tissue, which makes it difficult to attach to living bone. Ceramic coatings are made on the surface of these metal biomaterials, which improve the communication between the implant and the living tissue.Ti6Al4V substrates have been coated with a bioactive ceramic with composition 7CaO.P2O5.2SiO2 by Pulsed laser deposition (PLD). Layers have been deposited under different substrate conditions and their microstructure and composition have been characterized by XRD and SEM.
