“…The peak intensity of the β phase was higher than that of the α phase. However, addition of Zr resulted in a decrease in the intensity of the diffraction peaks, while peak width increased due to the accumulation of mechanical strain and reduction in crystallite size [1]. …”

Ternary Ti-Nb-Zr alloys were prepared by a magnetron sputtering method with porous structures observed in some of them. In bulk, in order to control the porous structure, a space holder (NH4HCO3) is used in the sintering method. However, in the present work, we show that the porous structure is also dependent on alloy composition. The results from Young’s modulus tests confirm that these alloys obey d-electrons alloy theory. However, the Young’s modulus of ternary thin films (≈80–95 GPa) is lower than that for binary alloys (≈108–123 GPa). The depth recovery ratio of ternary Ti-Nb-Zr thin films is also higher than that for binary β-Ti-(25.9–34.2)Nb thin film alloys.

“…21,22 On the other hand, the nano-sized roughness and Sr coating were achieved via magnetron sputtering, which is a physical deposition technique that enables the formation of nanostructured thin films and is widely used in several industrial applications with great success. 23 The technique has three remarkable advantages. First, a nanostructured coating can be deposited on the material surface; 23 in our study, layers of nanoparticles (diameters of approximately 20-40 nm) were fabricated through magnetron sputtering, and the same structure could also observed on the micro/nano surface.…”

We developed a hierarchical hybrid micro/nanorough strontium-loaded Ti (MNT-Sr) surface fabricated through hydrofluoric acid etching followed by magnetron sputtering and evaluated the effects of this surface on osseointegration. Samples with a smooth Ti (ST) surface, micro Ti (MT) surface treated with hydrofluoric acid etching, and strontium-loaded nano Ti (NT-Sr) surface treated with SrTiO 3 target deposited via magnetron sputtering technique were investigated in parallel for comparison. The results showed that MNT-Sr surfaces were prepared successfully and with high interface bonding strength. Moreover, slow Sr release could be detected when the MNT-Sr and NT-Sr samples were immersed in phosphate-buffered saline. In in vitro experiments, the MNT-Sr surface significantly improved the proliferation and differentiation of osteoblasts compared with the other three groups. Twelve weeks after the four different surface implants were inserted into the distal femurs of 40 rats, the bone–implant contact in the ST, MT, NT-Sr, and MNT-Sr groups were 39.70%±6.00%, 57.60%±7.79%, 46.10%±5.51%, and 70.38%±8.61%, respectively. In terms of the mineral apposition ratio, the MNT-Sr group increased by 129%, 58%, and 25% compared with the values of the ST, MT, and NT-Sr groups, respectively. Moreover, the maximal pullout force in the MNT-Sr group was 1.12-, 0.31-, and 0.69-fold higher than the values of the ST, MT, and NT-Sr groups, respectively. These results suggested that the MNT-Sr surface has a synergistic effect of hierarchical micro/nano-topography and strontium for enhanced osseointegration, and it may be a promising option for clinical use. Compared with the MT surface, the NT-Sr surface significantly improved the differentiation of osteoblasts in vitro. In the in vivo animal experiment, the MT surface significantly enhanced the bone-implant contact and maximal pullout force than the NT-Sr surface.

“…Moreover, magnetron sputtering involves a series of deposition parameters and variables that can be controlled for tailoring the structural and physical properties of the grown coatings [21][22][23]. The aim of this study is, therefore, to investigate the idea of moving from bulk materials to coated systems using magnetron sputtering as the deposition technique [24] while concurrently exploiting the microstructural and nanomechanical characteristics, such as to develop structureproperty relations. Through thin film technology, we attempt to stabilize the −phase of Ti − Nb alloys and introduce porosity by depositing the alloys at room temperature using relatively low ion energies.…”
