“…Post this behaviour, a dynamic stabilization is observed in the pH and corrosion rate values and a near uniform dissolution of the material is observed. However, with the passage of time, these reactions might continue to have a deeper impact along the matrix/particle interface, allows for the swelling of the composites due to electrolyte penetration, leading to the eventual failure of the composite [37]. Figure 6 shows the optical micrographs of the samples under immersion.…”

The design and development of novel magnesium-based materials with suitable alloying elements and bio-ceramic reinforcements can act as a possible solution to the ever-increasing demand of high performance bioresorbable orthopedic implant. In the current study, Mg-β-tricalcium phosphate composites are synthesized using the hybrid powder metallurgy technique, followed by hot extrusion. The influence of addition of (0.5, 1, and 1.5) vol % β-tricalcium phosphate on the mechanical, damping, and immersion characteristics of pure magnesium are studied. The addition of β-tricalcium phosphate enhanced the yield strength, ultimate compressive strength, and compressive fracture strain of pure magnesium by about~34%,~53%, and~22%, respectively. Also, Mg 1.5 vol % β-tricalcium phosphate composite exhibited a~113% enhancement in the damping characteristics when compared to pure magnesium. A superior~70% reduction in the grain size was observed by the addition of 1.5 vol % β-tricalcium phosphate particles to pure Mg. The response of Mg-β-tricalcium phosphate composites is studied under the influence of chloride environment using Hanks' balanced salt solution. The dynamic passivation was realized faster for the composite samples as compared to pure Mg, which resulted in decreased corrosion rates with the addition of β-tricalcium phosphate particles to pure Mg.

“…The corrosion action on the surface of the Mg-based materials usually starts with the electrolytic attack on the high-energy region at grain boundaries and the multiphase region with materials of different electrode potentials. The addition of HAp had little effect on the slight grain size reduction by providing additional nucleation sites during solidification and increased the volume fraction of grain boundaries . It favors the growth of the Mg(OH) 2 film.…”

“…The addition of HAp had little effect on the slight grain size reduction by providing additional nucleation sites during solidification and increased the volume fraction of grain boundaries. 58 It favors the growth of the Mg(OH) 2 film. The formation of the base metal and alloying element-based hydroxide films can initially provide passivation (with improved corrosion potential in the ZM31/HAp peak-aged sample), but due to the higher dissolution rate of Mg(OH) 2 in the presence of chloride ions in PBS, it leads to faster degradation.…”

The present work aims to assess the age hardening of microalloyed Mg–Zn–Mn alloy reinforced with Ca10(PO4)6(OH)2 (hydroxyapatite, HAp) particles to impart mechanical strength without deteriorating their degradation and biocompatibility behavior for their suitability toward resorbable fixation devices. The hydroxyapatite powder was synthesized with high purity. Mg–Zn–Mn (ZM31) and Mg–Zn–Mn/HAp (ZM31/HAp) were stir-cast, homogenized, and solution-treated to achieve uniform dissolution. Further, they were given a range of aging treatments (175 °C for 0, 5, 10, 25, 50, and 100 h), and the age hardening was measured as Vickers microhardness. The solution-treated and peak-aged (175 °C × 50 h) samples were further investigated using optical and electron microscopy, tensile testing, electrochemical corrosion testing, dynamic mechanical analysis, and biocompatibility. The peak-aged ZM31 sample revealed the highest ultimate strength (134.09 ± 5.46 MPa). The aging treatment resulted in notable improvement in ductility in ZM31 (8.72 ± 1.38%) and yield strength in ZM31/HAp (82.50 ± 1.43 MPa). The rapid strain-hardening behavior was distinctly visible in peak-aged samples in the initial stage of deformation. The amplitude-dependent internal friction confirmed the active solute and age-hardening mechanisms in agreement with the Granato–Lücke model. All samples displayed favorable cell viability (>80%) and cell adhesion behavior; however, their hemocompatibility and biodegradation need further consideration.

“…These Sn-based alloys exhibit strength, creep resistance, and biocompatibility. They have been widely employed in biomedical applications involving different parts of the human body, including bone tissue implants and dental implants (Kubasek et al, 2013;Shuai et al, 2016;Wang et al, 2015). Therefore, Sn-doped β-TCP scaffolds may improve the compressive strength of bone and promote osteogenesis.…”

Recent developments in 3D printing technology have been applied in the field of tissue engineering to fabricate customized bone repair scaffolds. β-tricalcium phosphate (β-TCP) is a bioceramic material with excellent potential as a scaffold foundation. Doping metallic ions with β-TCP will significantly enhance the mechanical property and bone regeneration performance compared with pure β-TCP specimens. In this study, we proposed a protocol for the fabrication of a Sn-doped β-TCP (Sn@TCP) scaffold using 3D printing technology, and the effect of Sn-doping on the physicochemical properties of the material and its in vitro bioactivity were investigated. Polyethylene glycol and polyvinyl alcohol were used as binder to construct Sn@TCP scaffolds which have good biocompability and can break down into H2O and CO2 after scaffolds sintering. The appearance of the scaffold constructed by 3D printing technology closely matched the computer design. The incorporation of Sn into β-TCP improved the compressive strength of the scaffold. Moreover, the Sn@TCP scaffold retained the inherently good biocompatibility of β-TCP and exhibited better osteoinduction capability than pure β-TCP scaffolds. Notably, the osteoinduction ability of Sn@TCP scaffolds were dependent on the Sn content. In conclusion, the 3D printing of Sn@TCP scaffolds with enhanced mechanical properties and osteoblast-inducing activity show great promise as scaffold materials in bone tissue engineering applications.
