However, its lack of antibacterial properties poses a limitation. To address this constraint, nanocomposite coatings with novel topographic microstructure and Ag, Cu nanoparticles are introduced onto the surface of pure Ti implants through sandblasting, acid etching, and hydrothermal treatment and magnetron sputtering. In addition, polished Ti substrates, Ti substrates subjected to sandblasting, acid etching, and hydrothermal treatment, as well as Ti samples individually magnetron sputtered with Ag and Cu, are fabricated and investigated. A systematic comparison between those samples is performed to investigate the influence of substrate surface microstructure and element composition on physicochemical characteristics and antibacterial performance of Ti implants. The results demonstrate that sandblasting, acid etching, and alkali heat treatment significantly enhance the surface roughness of pure Ti, thereby improving its wettability. Nano-Ag and nano-Cu particles are deposited via magnetron sputtering technology, resulting in excellent antibacterial properties. Compared to the single-layer coating, the nano-composite coating exhibited superior antibacterial activity despite releasing lower concentrations of Ag⁺ and Cu²⁺.

Deformation mechanisms are investigated to explore the role of topological architectures on mechanical response. Among the structures, the reverse hexagonal topology exhibits the highest yield strength and elastic stiffness, making it suitable for load-bearing applications. However, it demonstrates poor energy absorption due to its inability to utilize joints as plastic hinges during impact. In contrast, the octet structure exhibits superior energy absorption through a layer-by-layer collapse mechanism but offers limited elastic properties. The formation of shear bands in tetrakaidecahedron structure leads to midrange elastic properties. The spherical structure, however, shows poor energy absorption due to its unsystematic deformation and cell-wall distortion.
