“…In that case, we can make a comparison among different properties of porous Ti in the same preparing conditions. In addition, due to the active performance of Ti in the surrounding at high temperature [31], the high-purity argon (≥ 99.99%) was poured into the sintering chamber during the whole process to achieve the atmosphere requirements and remove potential trace…”

Porous Ti scaffolds with average pore size of 600 µm and porosity ranging from 31.1 to 61.2% were successfully prepared by powder metallurgy technology employing large size acicular urea as space holder. Results indicated that the porosity (P) of porous Ti could be determined accurately by added spacer content (S c) in the green-pressing because the relationship could be formulated as P = aS c + b, where a and b are constants. The compressive strength and structural stiffness were in the range of 50-332 MPa and 0.6-3.7 GPa, respectively. Moreover, the dependence between relative porosity and relative strength, along with the dependence between relative density and relative Yong's modulus were formulated. Our research can provide helpful information to fabricate porous Ti with desirable structure and mechanical properties by spacer method.

Accordingly, their properties are researched mainly on the biological performance and the relative mechanical characterization of the implant titanium foam with an interconnected open-cell porous structure, in main view of medical implant applications [9,[17][18][19][20]. As compared with this open-cell reticulated structure, cellular titanium foams have been quite rarely investigated [16].…”

“…In addition, the Ti-Mg alloy is also a biodegradable implant material, and the Mg in Ti-Mg alloys is biodegradable in the human body. The degradation process generates numerous pores, which facilitate the growth of cells and improve the bonding between the bones and implant materials [5][6][7][8].…”

Ti-Mg immiscible alloy thin films were prepared using a multi-arc ion plating technique with various deposition parameters. The surface and cross-section morphologies, crystal structures, and chemical compositions of the Ti-Mg films were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), and transmission electron microscopy (TEM). The influence of the substrate negative bias voltage and Ar gas pressure on the microstructure of the Ti-Mg films was systematically studied. Mg atoms were incorporated into the Ti lattice to form an FCC immiscible supersaturated solid solution phase in the thin film. Microparticles were observed on the film surface, and the number of microparticles could be significantly reduced by decreasing the substrate bias voltage and increasing the Ar gas pressure. The appropriate substrate bias voltage and Ar gas pressure increased the deposition rate. The TEM results indicated that columnar, nanolayer, and equiaxed nanocrystals were present in the thin films. Ti and Mg fluctuations were still evident in the nanoscale structures.
