Summary: Low-modulus beta-type Ti-45Nb alloy is a promising implant material with good mechanical biocompatibility, non-toxicity, and outstanding corrosion resistance. This study proposes a novel method to develop bioactive and antibacterial surfaces on Ti-45Nb alloy by incorporating gallium ions into hydroxyapatite. The results show that the combination of gallium and hydroxyapatite has great potential for local delivery of gallium ions and consequent antibacterial protection during bone regeneration.

Summary: This article presents a new metal coating method, which combines simultaneous precipitation and electrodeposition, to increase the integration ability of orthopedic and dental implants. The addition of Ca to the electrolyte results in more compact and uniform coatings, while the addition of P leads to more porous layers. Compared to the classical electrodeposition method, the new approach significantly increases the deposition of crystalline HA on various metal substrates, offering better crystallinity, more uniform and continuous surface, higher roughness, and potentially higher anti-corrosion capabilities.

Summary: A hydroxyapatite-carbon nanotubes (HA-CNTs) nanocomposite coating was applied to anodized Ti alloy using an electrophoretic method to investigate its stability in simulated body fluid (SBF). The coating was characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD), and the effect of CNTs concentration on coating properties was studied. The results showed that a CNTs concentration of up to 5% had various improving effects on the corrosion resistance, adhesion, and crack formation of the coating. In vitro tests demonstrated that cell viability increased with increasing CNTs concentration, reaching a maximum at 3 wt.% CNTs.

Summary: Single-layer and multilayer alloy deposits were electroplated onto a mild steel substrate, consisting of Zn and Fe alloys with different compositions. The corrosion resistance of these deposits was evaluated using potentiodynamic polarization method, while their surface morphology, crystal structure, and Fe content were characterized using scanning electron microscopy, X-ray diffraction, colorimetry, and energy-dispersive X-ray spectroscopy, respectively. The microhardness of the coatings was measured using a Vickers indenter. It was found that the Zn-Fe multilayer coatings showed significantly improved corrosion resistance compared to the single-layer coating, making them crucial for the automotive industry and steel-based vehicle parts.

Summary: In this study, fine particle peening using hydroxyapatite shot particles was conducted on a beta titanium alloy to improve fatigue strength and form a HAp transfer layer. The treated specimen showed increased surface hardness and the formation of a HAp transfer layer with high compressive residual stress. Rotating bending fatigue tests revealed that the fatigue strength at 10^7 cycles was higher for the FPP-treated specimen compared to the untreated specimen, due to the formation of a work-hardened layer with high compressive residual stress.

Summary: The phase evolution of alloys and atomic diffusion are closely related. However, the influence of reactive diffusion on phase formation in high-entropy alloys (HEAs) is still not clear. This study investigates the phase evolution of a multicomponent CoCrFeNi/Al diffusion couple and reveals the combined effects of enthalpy and entropy on phase formation in HEAs at elevated temperatures. Surface modification of HEAs can be achieved through film deposition and annealing processes.

Summary: In this study, CoCrFeMnNi high-entropy alloys with a surface gradient nanostructure were produced using industrial shot blasting, which significantly improved their mechanical properties. The severely plastically deformed surface layer had a multi-scale hierarchical structure and increased in depth with shot-blasting time. The microhardness and tensile strength of the alloy were significantly higher after shot-blasting. The improved strain hardening and prevention of early necking in the gradient-nanostructured surface layer contributed to its high toughness.

Summary: Tribo-electrochemical behavior of two beta-type (100-x)(Ti-45Nb)-xGa (x = 4, 8 wt%) alloys in physiological solution was investigated. Microstructure and mechanical behavior were evaluated by X-ray diffraction, microhardness and ultrasonic method. Tribocorrosion tests showed degradation mechanisms of plastic deformation, delamination, abrasive and adhesive wear. An improved wear resistance with lower damage was observed for beta-92(Ti-45Nb)-8Ga alloy due to increased microhardness. The addition of Ga to Ti-45Nb improved corrosion resistance under mechanical loading.

HPT processing extended the consolidation and deformation ranges for Fe73.9Cu1Nb3Si15.5B6.6, and achieved consolidation and deformation with minimum cracks for Fe81.2Co4Si0.5B9.5P4Cu0.8 for the first time. Various analyses revealed that Fe81.2Co4Si0.5B9.5P4Cu0.8 exhibited HPT-induced crystallization phenomena, while Fe73.9Cu1Nb3Si15.5B6.6 did not crystallize even at high HPT-deformation degrees.

Summary: Selective laser melting (SLM) was utilized to produce CuZrAl metallic glass (MG) scaffolds with combined lattice structures of body-centered cubic and face-centered cubic (F2BCC), and the effects of lattice structures on mechanical behavior were investigated. The results revealed that curved struts remarkably enhanced compressive ductility by 122% and energy absorption by 106%. The presence of curved struts effectively prevented catastrophic shear fracture and delayed fracture occurrence due to the release of strain concentrations. This study demonstrates the potential of improving the ductility and toughness of SLM MG components through appropriate lattice structure design.

Summary: This study focuses on the synthesis and properties comparison of a novel organic composite nanofiber material consisting of styrene-butadiene-styrene (SBS) copolymer blended with polystyrene (PStyr) and carbon nanotubes (CNTs). The addition of CNTs retards the crystallization process and decreases the absorbance of both SBS/PStyr and PStyr/PBu in Fourier transform infrared spectroscopy. The interaction of CNTs with the blend is limited in samples with SBS, as observed in Raman spectroscopy.
