TL;DR: In this article, a self-made induction nitriding device was used to nitride medical pure titanium (TA1), and the nanoindentation was performed by using Hank's solution.
Abstract: Titanium alloy is playing an increasingly important role in the field of biomedicine. However, poor wear resistance of titanium alloy will cause premature failure, which greatly limits its scope. Therefore, this study used a self-made induction nitriding device to nitride medical pure titanium (TA1), then the nitriding layer produced was characterized by XRD, SEM and nanoindentation instrument, and its wearability and corrosion behavior were tested, using Hank's solution. The tribocorrosion behavior and synergistic effect of the sample were studied by means of electrochemical measurement and surface morphology analysis. L-929 cells were also used to analyze the biocompatibility of the nitriding layer. The experiment result shows that TA1 titanium alloy can obtain a nitriding layer about 20 μm thick after 1 h's induction nitriding treatment, which effectively improves the mechanical properties, corrosion resistance and wear resistance of TA1 titanium alloy. Synergistic effects are produced in the process of tribocorrosion, and the corrosion weight loss caused by wear is dominant.

TL;DR: In this paper, vacuum induction nitriding technology is used to strengthen the surface of a Ti-25Nb-3Zr-2Sn-3Mo (TLM) alloy.
Abstract: In human implant materials, beta (β) titanium alloys have been extensively used because of their excellent biocompatibility and lower elasticity modulus; however, they have poor hardness and wear resistance. Herein, vacuum induction nitriding technology is used to strengthen the surface of a Ti–25Nb–3Zr–2Sn–3Mo (TLM) alloy. The nitriding layer microstructure is characterised using X-ray diffraction (XRD), scanning electron microscopy (SEM)–energy dispersive spectrometry (EDS) and optical microscopy (OM). The mechanical properties of nitriding layer are tested using cross-sectional hardness gradient and nano-indentation. Furthermore, the wear resistance and mechanism of nitriding layer are examined using a self-made reciprocating wear tester, a three-dimensional (3D) profilometer and SEM, respectively. The results demonstrate that an approximately 30-μm thick nitriding layer is formed on the TLM alloy surface after induction nitriding treatment. Interestingly, it forms a gradient structure that can improve the hardness and wear resistance of samples. Moreover, at a maximum test load of 10 N, the abrasion loss of the raw sample is 463 times that of the nitriding sample. Furthermore, the friction coefficient of the raw sample significantly exceeds that of the nitriding sample at three test loads. The wear mechanism between the friction pair Al2O3 ball and the raw sample is primarily a combination of abrasive and adhesive wear, whereas that of the nitriding sample is primarily abrasive wear. The results demonstrate that the nitriding layer significantly improves the wear performance of TLM alloys.

TL;DR: In this article , the adsorption capacity of PDA/PEI-TPU NFMs was evaluated using three anionic dyes: congo red (CR), sunset yellow (SY), and methyl orange (MO).
Abstract: Considering the notable mechanical properties of thermoplastic polyurethane (TPU), polydopamine–polyethyleneimine (PEI) -modified TPU nanofiber membranes (PDA/PEI-TPU NFMs) have been developed successfully for removal of anionic azo dyes. The adsorption capacity of PDA/PEI-TPU NFMs was evaluated using three anionic dyes: congo red (CR), sunset yellow (SY), and methyl orange (MO). Interestingly, it exhibited different adsorption behaviors and mechanisms of CR on PDA/PEI-TPU NFMs compared with SY and MO. With the decrease in pH, leading to more positive charges on the PDA/PEI-TPU NFMs, the adsorption capacity of SY and MO increased, indicating electrostatic interaction as a main mechanism for SY and MO adsorption. However, wide pH range adaptability and superior adsorption have been observed during the CR adsorption process compared to SY and MO, suggesting a synergistic effect of hydrogen bonding and electrostatic interaction, likely as a critical factor. The adsorption kinetics revealed that chemical interactions predominate in the CR adsorption process, and multiple stages control the adsorption process at the same time. According to the Langmuir model, the maximum adsorption capacity of CR, SY and MO were reached 263, 17 and 23 mg/g, respectively. After six iterations of adsorption–desorption, the adsorption performance of the PDA/PEI-TPU NFMs did not decrease significantly, which indicated that the PDA/PEI-TPU NFMs have a potential application for the removal of CR molecules by adsorption from wastewater.

TL;DR: In this paper , the surface of the TLM alloy was strengthened by induction nitriding technology, and the microstructure of the formed nitride layer as well as its corrosion property were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), and electrochemical workstation.
Abstract: Ti–25Nb–3Zr–2Sn–3Mo (TLM) alloys have been used in orthopaedics due to their excellent biocompatibility. However, the poor tribological performance caused by the low shear strength limits the applicability of TLM alloy. Herein, the surface of the TLM alloy was strengthened by induction nitriding technology, and the microstructure of the formed nitride layer as well as its corrosion property were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical workstation. The results showed that a gradient nitride layer with a thickness of ~30 μm was obtained on the surface of the TLM alloy after induction nitriding and the surface microhardness of the TLM alloy also increased from approximately 230 HV to 1253 HV. Meanwhile, the corrosion resistance of the TLM alloy in simulated body fluids (SBFs), was significantly improved by the nitride layer, which was supported by the corrosion potential value increasing from −665.77 (the raw sample) to −241.00 mV (the nitrided sample). Triborrosion behaviour is also characterized by a reciprocating sliding wear tester connected to an electrochemical workstation with different electrochemical conditions. The results evidenced that the TLM alloy has excellent tribocorrosion resistance after induction nitriding, who’s the mechanical material loss (WA) was only 0.23% of that of the raw sample under a 10 N load, and the total material loss (WT) was 15% of that of the raw sample.

Abstract: Ti and Ti alloys have charming comprehensive properties (high specific strength, strong corrosion resistance, and excellent biocompatibility) that make them the ideal choice in orthopedic and dental applications, especially in the particular fabrication of orthopedic and dental implants. However, these alloys present some shortcomings, specifically elastic modulus, wear, corrosion, and biological performance. Beta-titanium (β-Ti) alloys have been studied as low elastic modulus and low toxic or non-toxic elements. The present work summarizes the improvements of the properties systematically (elastic modulus, hardness, wear resistance, corrosion resistance, antibacterial property, and bone regeneration) for β-Ti alloys via surface modification to address these shortcomings. Additionally, the shortcomings and prospects of the present research are put forward. β-Ti alloys have potential regarding implants in biomedical fields.

TL;DR: In this paper, the influence of shot peening on the surface roughness, microstructure, micro-hardness, and tensile strength of TC2 thin-sheets with a thickness of 0.5mm was investigated systematically.
Abstract: The research aimed to find a physical strengthening method for thin-sheet metal parts using an ultrasonic shot peening (USP) method at room temperature. Herein, the influence of the USP treatments on the surface roughness, microstructure, micro-hardness, and tensile strength of the TC2 thin-sheet with a thickness of 0.5 mm was investigated systematically. The results showed that the Ra of the TC2 thin-sheets increased to 0.374, 0.418 and 0.479 μm after the USP treatments with the intensities of 0.189, 0.277 and 0.360 mmA, respectively. Compared with pneumatic shot peening (PSP) of similar Almen intensity, the surface quality of the alloy after USP treatment was significantly improved. The cross-sectional micro-hardness curves of the USP-treated TC2 thin-sheet showed ‘V’ shapes, and the micro-hardness of the surface layer increased as the shot peening intensity increased. When the Almen intensity was 0.360 mmA, the corresponding maximum micro-hardness of the surface layer was 362.9 HV0.025, which was 67.9 HV0.025 larger than that of the initial alloy. The USP treatment also improved the tensile strength of the TC2 thin-sheet, and the tensile strength increased as the shot peening intensity increased. When the Almen intensity was 0.360 mmA, the tensile strength was increased by about 6.23%, reaching 799.3 MPa. Therefore, the USP treatment method is a potential physical strengthening method for thin-walled parts at room temperature.

TL;DR: In this article , hollow cathode plasm source nitriding (HCPSN) was used to generate nitrided layers on the surfaces of Ti6Al4V titanium alloys to improve their corrosion resistance.
Abstract: Ti6Al4V titanium alloys, with high specific strength and good biological compatibility with the human body, are ideal materials for medical surgical implants. However, Ti6Al4V titanium alloys are prone to corrosion in the human environment, which affects the service life of implants and harms human health. In this work, hollow cathode plasm source nitriding (HCPSN) was used to generate nitrided layers on the surfaces of Ti6Al4V titanium alloys to improve their corrosion resistance. Ti6Al4V titanium alloys were nitrided in NH3 at 510 °C for 0, 1, 2, and 4 h. The microstructure and phase composition of the Ti-N nitriding layer was characterized by high-resolution transmission electron microscopy, atomic force microscopy, scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. This modified layer was identified to be composed of TiN, Ti2N, and α-Ti (N) phase. To study the corrosion properties of different phases, the nitriding 4 h samples were mechanically ground and polished to obtain the various surfaces of Ti2N and α-Ti (N) phases. The potentiodynamic polarization and electrochemical impedance measurements were conducted in Hank’s solution to characterize the corrosion resistance of Ti-N nitriding layers in the human environment. The relationship between corrosion resistance and the microstructure of the Ti-N nitriding layer was discussed. The new Ti-N nitriding layer that can improve corrosion resistance provides a broader prospect for applying Ti6Al4V titanium alloy in the medical field.
