Summary: Bone-like hydroxyapatite (HAp) was prepared from 1.5SBF with different pH values, resulting in micro-sized particles with higher Ca/P ratio and crystallinity at pH 7.4, and nano-sized particles at pH 8.0 and 8.4. A mixture of micro-sized and nano-sized particles was obtained at pH 7.7. Monitoring Ca2+ concentrations showed a drastic decrease at pH 7.4, slightly decreased at higher pH, and higher at pH 7.7. The cytotoxicity of the obtained precipitates to mesenchymal stem cells was lower than that of synthetic HAp.

Summary: Scientists have identified two main paths for orthopedic implant fabrication, either searching for new materials with properties closest to natural bone or creating individually adapted geometry with Rapid Prototyping methods. PEEK GRF30 and Ti6Al4V SLM are materials of interest, but further research is needed to fully understand their bioactivity. The study found that both materials exhibited bioactivity comparable to Ti6Al4V, showing promising potential for orthopedic implants.

Summary: Various surface modifications have been explored to enhance the apatite formation ability of EBM Ti-6Al-4V alloy. Among the methods tested, micro-arc oxidations in 1 M H2SO4 solution (SM) showed the best results in terms of apatite formation ability, which could be attributed to its high roughness, low contact angle, presence of Ti-OH groups, and anatase and rutile phases.

Summary: In this study, Ti-xFe (x = 3,5,9 wt%) alloys were surface modified by micro-arc oxidation (MAO) to improve their antimicrobial properties and biocompatibility. The results showed that increasing the oxidation voltage greatly enhanced the roughness and hydrophilicity of Ti-xFe-MAO alloys. The Ti-xFe alloys micro-arc oxidized at 250 V and 300 V exhibited improved corrosion resistance and excellent antimicrobial and cytocompatibility properties, making them suitable for orthopedic implant materials.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
