The results show that no chemical reaction occurred between the AZ91 matrix and the activated carbon particles. The mechanical properties of the foam were evaluated under quasi-static compression loading conditions, and showed a consistent trend for the energy absorption of the fabricated AZ91-AC syntactic foams. The deformation mechanism of samples was a brittle fracture mode with the formation of shear bands during the fracture of all samples.]]> Tue 02 Jul 2019 15:14:51 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29857 k-nearest neighbour algorithm for pore identification. The results indicate a weak density gradient parallel to the casting direction and a slight preference of particle orientation perpendicular to the casting direction.]]> Sat 24 Mar 2018 07:40:44 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43430 4) scaffold was produced using counter-gravity infiltration casting method and its in vitro degradation behaviour was evaluated using an electrochemical technique in simulated body fluid (SBF) for potential applications in bone fracture fixation devices. The porous zinc alloy exhibited porosity of ~60% with interconnected pores, and the pore size was 1–2 mm. The in vitro potentiodynamic polarization results showed that the degradation rate of the porous zinc alloy was 0.16 mm/year, which is ~15% higher than that of the non-porous pure zinc metal (0.14 mm/year). Highly biocompatible calcium phosphate (CaP) was electrochemically deposited on the porous zinc alloy and its in vitro degradation behaviour was also studied. The micrographs of the CaP deposited porous zinc alloy revealed uniformly coverage of CaP particles on the outer surface of the alloy and partial deposition on the inside of the pores. The morphology of the deposited CaP particles was predominantly spherical-shaped, but flake-like particles were also evident on the inside of the pores. Interestingly, the degradation rate of the CaP deposited porous zinc alloy (0.5 mm/year) was three times higher than that of the porous zinc alloy. It can be hypothesized that the restricted SBF flow through the partially blocked pores by the CaP particles have locally raised the pH inside the pores and thus increased the degradation.]]> Mon 19 Sep 2022 09:57:20 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33289 Fri 28 Sep 2018 15:54:19 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33288 Fri 28 Sep 2018 15:54:18 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48164 Fri 10 Mar 2023 16:46:38 AEDT ]]>
