Summary: In this study, composite structures made of hydroxyapatite scaffold impregnated with a collagen slurry were designed to mimic bone tissue structure, with the addition of magnesium and silicon ions enhancing mechanical and biological properties. An innovative freeze-drying approach was developed to create open-pore structures for tissue regeneration. The biodegradation behavior of the scaffolds, particularly HA-Mg_Coll scaffolds, showed moderate weight loss and mechanical performance reduction due to collagen dissolution, while also protecting the ceramic structure until degradation, making them suitable candidates for bone remodeling.

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: Micro arc oxidation (MAO) was used to modify the surface characteristics of AZ31 Mg alloy for implant applications, resulting in improved biocompatibility, corrosion resistance, and the formation of a calcium phosphate (Ca-P) containing thin film. After in-vivo implantation, the coating showed enhanced proliferation activity, better corrosion resistance, and lower roughness compared to mere MAO coatings on AZ31 alloy. This study demonstrates the potential feasibility of using MAO coatings for orthopedic implants in clinical applications.

Summary: A MgO-based bioactive coating consisting of SiO2 and HA was fabricated on AZ31 magnesium alloy using PEO method. The PEO process was performed in an electrolyte with optimized conditions, and SiO2 and HA were simultaneously synthesized in-situ over the PEO process. The results showed that the PEO coating containing both SiO2 and HA exhibited better corrosion resistance and higher potential for hydroxyapatite deposition compared to the PEO layer with only synthesized SiO2.

Summary: The main objective of the research is to improve the bonding of hydroxyapatite (HA) on the surface of titanium alloy, with a focus on the role of octadecylphosphonic acid (ODPA). The results show that ODPA can increase the precipitation of HA, while adding ODPA to annealed titanium alloy restricts the precipitation of HA on its surface.

Summary: In this study, the addition of (EDTA)4- in alkaline silicates electrolyte was found to result in thick and layered pancake-like materials with minimum cracks and porosity. The analysis also revealed that EDTA can significantly alter the surface layers composition and act as a passivation agent. However, no individual polycrystalline phases were formed. The corrosion potential of the coated AZ91 was positive, but the results were not consistent with the cyclic polarization tests.

Summary: Aluminium alloys, specifically the 6 xx series like AA6061-T6, are widely utilized in manufacturing industries due to their high strength to weight ratio, good ductility, excellent corrosion resistance, and relatively low cost. However, concerns arise when using friction stir welding (FSW) to join AA6061-T6 as it leads to significant deterioration in mechanical and tribological properties. This is primarily attributed to the severe softening phenomenon encountered at the stir zone, along with other challenges like weld thinning and keyhole formation. Various improvement strategies have been reviewed to enhance the quality of AA6061-T6 welded joints, including parametric optimization, tool design, heat treatments, groove/hole designs, and reinforcement particle addition. This review will prove beneficial for future studies on FSW of heat treated aluminium alloys.

Summary: The study found that increasing the number of weld passes improves matrix refinement and particle distribution in AA6061-T6 friction stir welded joints, while increasing SiC content leads to particle clustering. All reinforced joints showed higher hardness but lower ductility, with the best combination of properties observed in joints reinforced with 0.56 g SiC addition at 4 weld passes.

Summary: In this study, the optimum conditions for producing circular, ordered, and uniform nanoporous anodic film were investigated by studying the effect of anodization voltage and electrolyte temperature. Increasing the applied voltage resulted in larger pore diameter. The as-anodized film consisted of nanocrystallites that transformed into orthorhombic Nb2O5 after annealing. Interestingly, the as-anodized Nb2O5 exhibited better photoreduction of Cr(VI) compared to annealed Nb2O5, though the annealed Nb2O5 showed higher photocatalytic efficiency and stability.

Summary: An in situ nanostructured copper tungsten carbide composite was synthesized by mechanical alloying and powder metallurgy. Tungsten carbide phases (WC and W2C) were only present after mechanical alloying and sintering. The formation of WC was influenced by the energy associated with longer milling time. The formation of W2C and WC resulted from internal refinement due to heavy plastic deformation in the composite.
